Type 301 (UNS S30100) is an austenitic stainless steel used in annealed and cold-worked conditions. Strength, ductility and magnetic response depend on material condition; a grade name alone does not establish acceptance properties.
The former blanket strength values and the description of MPa as hardness have been withdrawn. Specify tensile strength and yield strength with units such as MPa, and specify hardness with its test scale and method. Do not infer one from the other without an applicable, validated basis.
Reference: ATI 301 technical data sheet (2014), pages 3–5. Its condition-dependent reference data are not a Myriad supply guarantee. Third-party stock ranges and legacy delivery promises do not establish Myriad availability; confirm the required grade, temper, dimensions and documentation for each enquiry.
Type 301 is an austenitic stainless steel. Cold working can increase strength, while ductility depends on material condition and processing history; higher strength must not be read as a simultaneous increase in ductility.
Properly annealed 301 has low magnetic permeability. Cold working can form martensite and increase magnetic response, as described in the cited ATI 301 data sheet. The former blanket comparison with 201 and other austenitic grades has been withdrawn. Verify properties for the specified material condition rather than treating the grade name as an acceptance result.
ATI lists the following reference chemistry for Type 301 (UNS S30100), in weight percent: C 0.15 max; Mn 2.00 max; P 0.045 max; S 0.030 max; Si 0.75 max; Cr 16.00-18.00; Ni 6.00-8.00; N 0.10 max. Confirm the applicable product standard, edition and material certificate for an order; this reference is not a Myriad supply guarantee.
Reference: ATI 301 technical data sheet (2014), page 1.
ATI gives representative values for annealed Type 301: density 8.03 g/cm³; melting range 1399–1421 °C; tensile elastic modulus 193 GPa. Its data sheet lists electrical resistivity of 72 µΩ·cm at 20 °C and specific heat of 500 J/(kg·K) over 0–100 °C. These are reference data, not product acceptance limits or a Myriad supply guarantee.
Reference: ATI 301 technical data sheet (2014), pages 2–3.
The former claim that a secondary annealing step automatically restores corrosion resistance after laser cutting has been withdrawn. This guide does not establish a qualified heat-treatment or surface-restoration procedure.
ATI notes susceptibility to carbide precipitation during welding. Corrosion performance and processing suitability require assessment for the actual material condition, fabrication history and service environment; a general application list does not qualify material for medical, food-contact or water-contact service.
The former statement that 301 cannot be held on a grinding-machine magnetic table has been withdrawn. Magnetic response alone does not qualify or disqualify a workholding arrangement.
Confirm the actual material condition and magnetic response, workpiece thickness, contact area and surface condition, chuck configuration and machining loads. Have the workholding arrangement assessed and verified against the equipment manufacturer’s instructions for the actual operation; this guide does not provide a validated setup or holding-force guarantee.
For applications involving stainless steel coil, confirm the specified product and component requirements. The linked third-party page is not evidence of Myriad supply capability.
The former 60–280 ksi range and comparison of 301 with 301Si were not accompanied here by a traceable specification, material condition, dimensions or test record. They must not be used as universal 301 acceptance limits or as evidence that grade variants are interchangeable.
Specify the applicable material standard, product form, temper and required yield strength, including units and test method. Verify the supplied material against the governing specification and traceable test documentation.
The former wording about chemical solutions increasing ductility at a maximum-strength temper did not identify a verified composition, material condition or process and has been withdrawn.
Select the specified 301 grade and condition against documented mechanical-property requirements and actual forming trials. This guide does not establish that a chemistry change will improve ductility at a given strength, or that 301 and 301Si can be substituted without verification.
A rolling-mill type or automated gauge-control system alone does not establish an achievable tolerance for a specific 301 strip order. The former promise of extremely tight tolerances has been withdrawn.
Agree the required dimensions, tolerances, material condition and inspection method. Confirm the proposed process and documented results for the actual order; this guide does not establish a Myriad rolling capability.
This guide does not verify a Myriad continuous-furnace stress-relief process or delivery capability. Confirm any proposed processing route for the specific enquiry.
Stress-relief results depend on the material condition and qualified treatment cycle. Confirm the procedure and verify the required mechanical properties against documented test results; this guide does not establish a universal increase in strength or hardness, or a universal reduction in elongation.
The former .025 threshold for selecting a leveling or rolling process has been withdrawn because its unit, source and applicable equipment conditions were not established. Do not use it as a process-selection or acceptance limit.
For 301 strip, agree the flatness requirement and measurement method for the specified thickness, width and material condition. Qualify the proposed process and verify the finished strip against documented inspection results.
Camber refers to edgewise curvature of strip. Specify the permitted deviation over an agreed measuring length, together with the material condition, dimensions and inspection method.
The former wording did not establish a usable measurement or acceptance requirement. Confirm the applicable specification and order criteria; this guide does not establish a universal camber limit or a Myriad capability guarantee.
Material chemistry and mechanical properties alone do not establish that a specified bend can be formed. Define the required material condition, thickness, bend geometry and direction, tooling and forming sequence.
Qualify the actual part and inspect it against agreed requirements. This guide does not establish a universal bend radius, crack-free result or springback allowance.
The former statement that springback can easily be solved by tighter chemistry and a production range has been withdrawn; this page does not provide verified forming trials supporting that conclusion.
For a stamped part, specify the material condition, dimensions, tooling, forming sequence and final geometry requirements. Establish and verify any springback compensation through documented trials for the actual part; chemical composition alone is not an acceptance result.
301 stainless steel gains strength through cold working. Tensile strength, yield strength, hardness and elongation depend on material condition and processing history. A single strength value does not describe every 301 strip product.
Specify the required temper and acceptance criteria, and verify the supplied material against the applicable specification and test results.
ATI’s 2014 Type 301 data sheet lists examples such as railway and subway cars, automotive trim and springs. These are examples of grade applications, not qualification of every 301 strip condition for those uses.
The former broad industry list and unspecified reference to ASTM have been withdrawn as selection guidance. Identify the applicable product standard and edition, material condition, dimensions, forming requirements and service environment for the actual component.
Use documented material and application evidence to confirm suitability. This guide does not establish suitability for food-contact, chemical, marine or other regulated or demanding service, or a Myriad supply capability, from a general application list.
The former description of diamond internal circular blades as mainly used for artificial crystal, single-crystal silicon and ceramics has not been verified for the blade design or 301 substrate discussed here. This guide does not establish that 301 strip is suitable for a particular cutting application.
The former claims of a small cutting slit, good cutting flatness and wear resistance are not supported here by traceable application tests. Do not infer cutting quality, wear performance or service life from the 301 grade name or strip properties alone; verify the complete blade and cutting process against the application requirements.
The former statement that 0.12 mm SUS301 strip is mainly used for diamond-blade substrates has not been verified. A thickness alone does not qualify a substrate or establish a Myriad supply offer. Specify the required material condition, thickness and tolerance, flatness, edge and surface requirements, and verify the actual blanking or stamping results for the blade design. This page does not establish a universal no-warpage result.
The legacy case below reports hardness of 490–530 HV, tensile strength of 1650–1800 MPa and elongation of 2–4%. Its source, test conditions and customer approval have not been verified. These figures do not establish a 1/2-hard temper and are not Myriad supply or acceptance limits. Specify the applicable standard, thickness, temper and test requirements before acceptance.
Material properties and strip shape are requirements to define and verify, not a validated production method. Establish the required material condition, dimensions, flatness, edge and surface quality, and acceptance documentation for the actual substrate design. Any proposed processing route and finished blade performance require separate qualification; this guide does not establish a Myriad production capability.
The former claim that we optimized and repeatedly tested a best production process has been withdrawn. This guide does not provide traceable trial records, a verified experiment owner or customer-approved results establishing a Myriad production capability for diamond-blade substrates.
Reference for condition-dependent 301 properties: ATI 301 technical data sheet (2014), pages 4–5. The remaining legacy experiment descriptions require separate verification.
The former starting-strip dimensions of 1.2 mm by 270 mm and coil mass of about 1.5 t have been withdrawn as an unverified case description. This page does not identify traceable material or trial records establishing those values as a qualified production input.
Specify and verify the actual starting grade, material condition, dimensions and traceable material documentation for a qualified process. These legacy values are not Myriad stock, equipment or supply limits.
The former single-row chemical analysis has been withdrawn because this page did not identify its source, heat or lot number, analysis method or traceable material certificate. It must not be used as the general composition range for Type 301 or as a Myriad test result.
For reference chemistry, see the cited Type 301 chemistry section above. Verify an order against the applicable material specification, edition and traceable material documentation; reference limits and an individual analysis are different types of evidence.
Cold rolling changes the mechanical properties of 301 stainless steel. The required rolling schedule must be qualified for the starting material, final thickness, target temper and application.
A reduction percentage alone does not establish finished hardness, tensile strength, yield strength or elongation. Use documented process and material test results to confirm these properties. A process example does not establish equipment capability, available stock or the feasibility of a specific supply combination.
The former straightening settings and reported I-unit results have been withdrawn because their source, equipment configuration, measurement method and trial records have not been verified.
This guide does not establish a universal elongation or tension setting for 301 strip. Qualify the leveling procedure for the actual grade, temper, dimensions and equipment. Agree the flatness requirement and measurement method, and verify the finished material against documented inspection results.
This guide does not establish that stress-relief annealing and tension annealing are interchangeable terms, or that stress relief necessarily uses a continuous line under tension. The former general definition and guarantees of stress removal and reduced cracking have been withdrawn.
The former 0.12 mm strip and two-metre sampling sequence did not identify a traceable experimental source, equipment setup, sampling plan or test method and has been withdrawn as an operating or validation procedure. Qualify the actual treatment and inspection plan for the material and application; this page does not establish a validated process.
Stress-relief treatment can change the mechanical properties of cold-worked 301 stainless steel. The result depends on the material condition and the qualified treatment cycle.
A temperature or line-speed setting alone does not establish an optimum process or guarantee customer acceptance. Confirm the treatment procedure and verify the resulting hardness, tensile strength, yield strength, elongation and flatness against documented test methods and agreed acceptance criteria for the actual material.
The former claims of gap-free flatness, no warpage after cutting, and a blade life of about 1,500 uses have been withdrawn because the underlying test records and application conditions have not been verified.
A visual fit against a platform does not establish a quantified flatness limit or service life. Define the specimen, inspection condition, measurement method and acceptance criteria for flatness. Any blade-life claim requires separate, traceable application testing; this guide does not establish a Myriad performance or supply guarantee.
Type 301 can be cold worked to higher strength, but the term “spring tempered” alone is not a complete material specification or a qualification for a spring component.
Specify the applicable standard, temper or required mechanical properties, dimensions and inspection methods. Confirm the forming requirements and validate the finished spring against its design and service conditions; this guide does not establish elasticity, fatigue life or suitability from the grade or temper name alone.
This guide addresses 301 strip. The former round-bar application list has been withdrawn because this page does not provide product-specific evidence qualifying 301 bar for the listed uses.
Round bar requires a separate assessment of the applicable product specification, material condition, dimensions and service requirements. Do not transfer strip reference data or application examples to bar without verification; this guide does not establish a Myriad round-bar supply offer.
Type 301 is an austenitic stainless steel. In the properly annealed condition it has low magnetic permeability; cold working can form martensite and increase the magnetic response. The response depends on composition and processing condition. Where magnetism matters, specify the material condition, test method and acceptance limit.
Type 301 is an austenitic stainless steel (UNS S30100). For reference chemistry, use the sourced Type 301 chemistry section above rather than a second, conflicting list.
The former duplicate list, including a 1% silicon maximum, has been withdrawn because it did not identify a governing specification or edition and conflicted with this guide’s cited reference. ATI’s 2014 data sheet lists 0.75% silicon maximum; this is a source-specific reference, not a universal substitute for the applicable order specification.
Confirm the specified grade, standard and edition, and verify the supplied material with traceable documentation. A composition list alone does not establish finished strength, corrosion performance or Myriad supply capability.
The former blanket statement that 301 strip is easy to bend without fracturing has been withdrawn. Do not infer forming suitability from the grade name alone.
Evaluate the specified material condition, thickness, bend geometry and direction, tooling and forming sequence. Qualify the process for the actual part and inspect the result against agreed acceptance requirements; this guide does not establish a universal bend radius, crack-free result or springback allowance.
This guide does not provide a current price, surcharge schedule or pricing formula for 301 strip. A market-price comment alone is not a quotation for a specified product.
For a quotation request, state the applicable grade and product specification, material condition, thickness, width, tolerances, surface and edge requirements, quantity, documentation and delivery requirements. Confirm the quoted currency, commercial terms and validity with the supplier; this page does not establish Myriad pricing, availability or delivery commitments.
The former list of “leading manufacturers” has been withdrawn because this page did not provide current, product-specific sources or a ranking method. This does not determine whether any previously named company supplies a particular 301 product.
Check a proposed supplier against current documentation for the actual 301 product form, material condition, dimensions, traceability and acceptance requirements. Distinguish the material producer, processor and selling entity; a company name alone does not establish product availability, qualification, ranking or a relationship with Myriad.
Stainless steel strip may form part of a cable-tray design, but a material description alone does not establish the performance of the assembled system. The considerations below require project-specific verification.
These considerations do not qualify a cable-tray system or a particular 301 strip product. Verify the project requirements and the actual system evidence before selection; this guide does not establish a Myriad system-performance or supply guarantee.
