Grade 201 stainless steel has good formability, corrosion resistance, ASTM A240 Grade 201 Steel is similar to that of 301 stainless steel. Grade 201 stainless steel is used in structural members, different kinds of severely formed parts, and siding and roofing for railway cars and trailers.

Corrosion Resistance
Refer to NACE (National Associate of Corrosion Engineers) for recommendations
Cold Forming
201 is considered a formable stainless and is often drawn, stamped and headed. It work hardens easily and should be followed by anneal.
Heat Treatment
201 cannot be heat treated for hardness. Hardness can only be achieved by cold working.
Welding
Refer SSINA for Welding Recommendations
