The Ultimate FAQ Guide

Next, we will introduce you more details about ss301:



Type 301 Stainless Steel, also known as UNS S30100, is common stainless steel with austenitic chromium and Nickel with excellent corrosion resistance. SS301 has Nickel, and chromium levels are smaller. Ratios, which expands its cold work-hardening range. SUS301 is also an austenitic stainless steel high-strength alloy with strong resistance to corrosion in mildly corrosive conditions. 


Stainless Steel Chemical Composition – YAOYI Stainless Steel


Part 1

Stainless Steel 301 is stainless steel that is austenitic and has a nominal hardness of 304. chromium and nickel content of 17% and 7%, respectively. This steel grade is an outstanding choice for decorative structural applications due to its high strengths in the six available environments or tempers, resistance to atmosphere corrosion, and clear, attractive surface. Any of the main uses for this flexible grade include automobile molding and trim, wheel covers, conveyor belts, kitchen appliances, roof drainage systems, hose clamps, springs, truck and trailer frames, and railway subway vehicles. It will obtain a wide variety of materials, a range of magnetic and mechanical properties—the applications by modifying the chemical composition within limits defined by requirements and temper rolling. 


Part 2

This type, 301, is a chromium-nickel austenitic stainless steel, comes in annealed and cold-worked forms. Moreover, type 301 has the highest Any stainless steel has the potential to stretch. After annealing it, the highest strength rating of any stainless steel in the 300 series steel when heavily cold worked. Kind 301 is non-magnetic when annealed but becomes magnetic after cold operating. 

While ss301 is corrosion resistant in various environments, its corrosion properties are inferior to those of 304/304L Stainless steel is a durable material. 

The Type 301s vulnerability to carbide deposition during welding limits its usage in certain applications, whereas for welding applications, 304L, as a result of reduced carbon content.

Part 3

Stainless steel ss301 is widely supplied as strips and wires with tensile strengths up to 1800 Mpa, allowing tempers ranging from 1/16 Hard to Complete Hard to be made. As a result of the testing that ss301 undergoes, the controlled examination is capable of maintaining adequate ductility even in 12 hard environments. In the vehicles industry, they use Grade 301, also for rail car parts and architectural structures.

This grade of temper, with harnesses Various hardnesses, ranging from 34 to full hardness, also in applications requiring high wear resistance and spring characteristics in basic type designs. 

Part 4

Grade 301L, the carbon-free version of ss301, is an excellent option for applications requiring high ductility. In addition, Another variant is grade 301LN. When compared to norm 301, this has a greater nitrogen content percentage and a higher work-hardens score. 

This only specifies ss301. Other conventions reflect 301L and 301LN. JIS G4305 represents grade 301L, and EN10088-2 represents grade 1.4318 for grade 301LN.

How To Find The Right Stainless Steel Supplier


Stainless steel ss301 has a corrosion resistance that is equivalent to that of the stainless steel grade 304. This rating has excellent corrosion resistance in mildly corrosive conditions at room temperature. 


Type 301 can withstand a wide variety of corrosive substances and media. The corrosion properties, however, are not as strong as those of 18-8 chromium-nickel steels. Its resistance to carbide deposition during welding is using in fewer applications than  Types 304 or 304L. 


Heat Tolerance ss301 has excellent oxidation resistance for sporadic applications up to 840°C and continuous applications up to 900°C. 


ASTM A167: Composition, Properties, and Equivalent Grades


SS301 annealed in solution at temperatures ranging from  1010 degrees Celcius to 1120 degrees Celcius, accompanied by accelerated cooling. Besides, a low-temperature range used for intermediate annealing. This stainless steel is not suitable for thermal hardening.


J2 Stainless Steel: A Complete & Thorough Guide


Form 301 stainless steel and its low carbon variants are often used as high-strength stainless steels. These grades’ work hardening rates are very high, ranging from a 14MPa increase per 1% reduction in the area of cold to a 14MPa increase per 1% reduction in the area of hot work to a 14MPa increase per 1% reduction in the area of cold work. Cold rolling and roll forming operations can reach high strength as a function of this personality trait. 


Strain hardened austenite can be partially converted to martensite using certain shaping techniques. After reaching such high strengths, the alloy’s residual ductility is capable of producing extreme cold deformation. When annealed, the alloy is non-magnetic, but when cold worked, it exhibits heavy magnetism. 


J3 Stainless Steel : A Complete Guide For Importers


When cold worked, the SS301 a high-strength austenitic alloy with good ductility properties. The material is readily welded and has superior corrosion resistance. One of its main benefits is its excellent elasticity.


When cold work, the metal is malleable and ideal for all types of welding. This 301  

stainless steel is also easily molded and drawn. Form 301L is the low carbon variant of Type 301 and is ideal for applications requiring high ductility. SS301 stainless is suitable for various industries such as aerospace, rail, and automotive due to its high strength and outstanding corrosion resistance. 


What is J4 Stainless Steel? (And What Is It Used For)


Stainlesssteel 301 is appropriate for all regular welding processes. We suggest that regard grade308L  as filler metal. To achieve optimum corrosion resistance, ss301 welded parts must use annealing. After welding, we do not need to anneal for grades 301L and 301LN. Welding and annealing aim to get rid of the high strength that cold rolling causes.


The cold-rolled 301 pieces are assembling by spot welding; this fast welding the procedure does not compromise the component’s overall strength.
