Myriad's stainless steel coil slitting supply options

Myriad’s confirmed capability is to supply foil and strip with slitting and edge-processing options, subject to specification review. The table below describes the current overall supply range. It is not a machine-capacity table, a stock list or a promise that every listed dimension and grade can be combined.

Material thickness0.01–0.30 mm, approximately 0.000394–0.011811 inGrade, width, material condition and edge combination
Finished coil / strip width1.5–620 mm, approximately 0.0591–24.4094 inThe complete specification and required finished-width tolerance; this is not a parent-coil inlet-width rating
Minimum width at 0.01 mm thickness4 mm, approximately 0.1575 inRequired grade, condition, edge and tolerance; the overall 1.5 mm width minimum does not apply to this thickness
Grades available for quotation301, 304, 304L, 316, 316L, 309S and 310SGrade-specific dimensions and properties; listing a grade does not establish stock or dual certification
Edge-processing optionsStandard slit, deburred, rounded/conditioned and scraped edgesRequired edge profile, burr limit, dimensions and acceptance method
Surface optionsBA and 2B are the main options; mirror finish requires separate reviewSurface appearance and protection requirements for the selected configuration

Use these ranges to start an inquiry, then confirm the actual finished specification. Millimeters control the dimensions above; inch figures are approximate conversions. The maximum finished width does not establish the maximum parent-coil width that a particular slitting line can accept.

Smaller quantities can be reviewed without assuming an automatic MOQ exception. The regular MOQ is 100 kg of one identical specification within an order: the same grade, thickness, width and condition. Matching coils may be totaled; different specifications may not. Requests below 100 kg require a separate application and confirmation. Samples are chargeable, quoted individually, with freight paid by the customer.

Identify customer-supplied material as a separate service request. If you are looking for stainless steel coil slitting services for a coil you already own, state that at the start. The supply options above do not establish acceptance of customer-owned coils or the terms of a toll-processing order.

02

What stainless steel coil slitting changes

Stainless steel coil slitting divides a wider coil lengthwise into narrower strips that can be rewound as individual slit coils. For a buyer, the useful result is material that meets the required width, edge condition and winding requirements—not simply a coil cut into more pieces.

Understand stainless steel coil slitting, compare width and edge requirements, and review Myriad’s foil and strip supply options before requesting a quote.

01

Slitting establishes strip width; cold rolling establishes reduced thickness. A slitting order therefore needs the incoming material thickness and delivery condition as well as the finished width. Cutting a coil narrower is not a way to turn thicker stock into foil or establish a particular hardness.

02

A stainless steel slit coil is a delivery form, not a complete material specification. The grade, condition, thickness, width tolerance, edge, surface and coil configuration still determine what you are buying. “Precision slit” alone does not define an acceptance limit.

03

Choose width for the next operation, with the handling requirements included. Stamping or coil-fed forming may need continuous strip that feeds consistently; flat-part processing may need cut-to-length sheets instead. Define the required delivery form before comparing quotations.

03

How stainless steel coil slitting works

A slitting line combines cutting with controlled material handling. The basic route is parent coil → uncoiling and guiding → rotary slitting → separation and rewinding → inspection and packing. The following explains the process; it does not prescribe machine settings or operating procedures.

Parent coil Uncoil & guide Slit lengthwise Rewind Inspect & pack
01

Review the parent material. The grade, thickness, condition, surface and starting coil configuration establish the processing requirements. Finished strip requirements must be considered alongside the starting material.

02

Configure the cutting arrangement. Circular knives and their positioning establish the intended strip widths. Tool condition and the cutting setup affect the edge produced; the buyer specifies the required result rather than a universal knife-clearance setting.

03

Cut the material lengthwise. Several strips may be produced in one pass. The number of cuts and usable output depend on the material, layout and process, so do not assume a fixed yield from parent-coil width alone.

04

Control strip movement and rewind. The slit strips need suitable handling and winding. Tension that is inappropriate for the material can lead to distortion, breakage or loose winding; the target is a usable coil for the next operation.

05

Check the agreed requirements and protect the material. Width, edges, surface and coil condition require an agreed inspection basis. Packing then needs to suit shipment and subsequent handling.

Equipment selection depends on more than maximum width. Material thickness, width, coil weight, and surface requirements all influence the slitting of stainless steel.

Define width, edges and winding for stainless steel slit coil

Specify finished width and edge quality as separate acceptance requirements. A strip may meet a width measurement while still having an unsuitable edge or shape for your process. A single word such as “precision” or “burr-free” leaves the parties without a shared numerical or inspection basis.

Acceptance to agree

Simplified edge-profile concepts, not acceptance drawings. Required profile and dimensions need confirmation.

A slit edge does not automatically include deburring or a rounded profile. Those are different requirements and may involve additional edge processing. Generally speaking, when placing an order, you need to clarify with the customer whether deburring is required; state the finished edge you need rather than assuming it follows from slitting.

Burr height needs a measurement basis when it matters to the part. A burr is an unwanted metal projection at an edge. Specify the limit, relevant edge and inspection method.

Camber is different from width error. It is sideways curvature in the strip plane and can cause tracking difficulties even when the width is acceptable. Slitting may release residual stresses, so cutting does not guarantee removal of incoming shape problems. The acceptance length and method still need agreement for your strip.

Winding requirements belong in the RFQ. A coil with the correct metal dimensions may still be inconvenient for your payoff equipment if its core, outside diameter or unit weight is unsuitable. Give your equipment limits and ask for a confirmed coil configuration; no universal ID, OD or coil-weight limit is implied by Myriad’s thickness and width range.

05

Choose the grade and condition before coil slitting

A grade and delivery form alone do not establish

Hardness.
Tensile strength.
Forming allowance.

Define the material properties separately from the width-conversion process. “301 stainless steel slit coil,” for example, identifies a grade and delivery form but does not establish a spring condition, hardness, tensile strength or forming allowance. Include the required condition and any known numerical properties in the inquiry.

For a 301 stainless steel coil order, use the properties already established for the component. Send the required standard and edition, thickness, finished width and tolerance, condition, known hardness and/or tensile limits, and edge requirements. Do not substitute an assumed property range because another 301 coil used the same temper name.

When properties are undecided, explain the processing problem that needs a decision. Relevant forming, feeding, contact or service requirements help frame the discussion. A proposed material condition or property value still needs the buyer’s confirmation before it becomes an order requirement.

06

Inspect and pack stainless steel slit coils to agreed requirements

Agree acceptance before material is ordered. Decide which dimensional, edge, surface and coil-condition checks are required, with appropriate measurement methods and sampling. Thin foil requires particular care in handling and support; the measurement procedure must suit the material rather than distort what is being assessed.

Match the report package to the order. Do not assume that a material report verifies every finished slit-edge or winding requirement. Confirm what each document and inspection covers, and specify any additional testing that is needed. Myriad sends the applicable material reports for customer confirmation before shipment; routine delivery also requires settlement of the balance payment, with exceptions requiring separate approval.

Select packing for both transport and unpacking. Myriad offers moisture-protective packing, pallets, wooden cases and customer-specified arrangements, with wooden cases the principal option. The actual combination is agreed for the order. Include unit-weight, handling, surface-protection and labeling needs; do not assume a particular wooden-case certification from the packing name alone.

Request stainless steel coil slitting support from Myriad

Send a complete specification directly when the material requirements are settled. There is no need to supply a drawing or repeat application details unless they resolve a particular gap. This checklist helps keep the quotation and acceptance requirements aligned:

Ask for selection advice when a requirement is still open. Identify the undecided item and describe the relevant component function, forming process or service conditions. Include a drawing when it answers that specific question. Myriad can review the inquiry and clarify the proposed supply specification; supply and commercial terms require confirmation for the order.

  • Grade and governing product specification, including edition and unit system.
  • Thickness, finished slit width and dimensional tolerances.
  • Delivery condition and known hardness and/or tensile requirements, including the relevant test basis.
  • Edge profile, burr requirement, camber or surface criteria that affect the next operation.
  • Quantity for each identical specification, plus core/ID, maximum OD, coil weight and winding requirements.
  • Required inspections, reports, packing, destination and schedule.
  • Whether you need Myriad-supplied material or are asking about processing material you already own.
