Grade 304 is the standard "18/8" stainless; it is the most versatile and most widely used stainless steel, available in a wider range of products, forms and finishes than any other. It has excellent forming and welding characteristics.
Cold working is also referred to as work hardening or strain hardening. As a metal is cold worked, the strength and hardness increase while ductility decreases. Eventually, it is necessary to anneal the piece to allow further forming operations without the risk of breaking it. In addition, some metals are strengthened pri-marily by cold working.(plate) 301 STAINLESS STEEL(steel) Dec 13, 2016301 STAINLESS STEEL 1 Type 301 is an austenitic chromium-nickel stainless steel that provides high strength and good ductility when cold worked. It is a modification of Type 304 in which the chromium and nickel contents are lowered to increase the cold work-hardening range. This permits higher tensile
Type 301 is an austenitic stainless steel capable of attaining high strengths and ductility by cold working. It is not hardenable by heat treatment. Type 301 is non-magnetic in the annealed condition and becomes increasingly magnetic with cold working.
