Grade 301 is a 17% Chromium / 7% Nickel austenitic stainless steel. It is supplied in a range of different conditions/tempers depending on the level of strength required. It has good resistance to atmosphere corrosion and its bright attractive surface make it an excellent choice for decorative structural applications.
Resistance to Corrosion & Oxidation
Grade 301 has good resistance to oxidation at temperatures up to 1550°F, but is not recommend for use above 1600°F. 301 is resistance to a variety of corrosive media. However, it's corrosion resistance properties are not as good as the 18-8 chromium-nickel steels and its susceptibility to carbide precipitation during welding restricts its use in many applications in favour of 304/304L alloy. The mechanical properties for the different tempers of 301 are obtained by cold working and not by heat treating. 301 1/2 Hard (AMS 5518) material has a miniumum tensile strength of 150ksi and is used in the fabrication of parts that require strength and involves moderate drawing or forming.

Magnetic properties:
301 stainless steel flat rolled coil is non-magnetic in the annealed condition but becomes magnetic when cold worked.
Forming:
Type 301 is used in fabrication by bending, roll forming, blanking, stretch bending and drawing. It’s high work hardening rate helps minimize wall thinning when deformed. Deep drawing may require intermediate annealing or higher nickel content.
