Typical applications for Types 201 are cookware, hose clamps, piston rings, transit car structural member, transit car roofing/siding, thermal window spacers, air bag containers, and truck trailer posts and door frames.
The annealing temperature for Type 201 is between 1850-2000°F. Rapid cooling through the carbide precipitation range (1500 – 800 o F) is necessary to keep the carbides in solution and prevent sensitization. Type 201 is not hardenable by thermal treatment; it is only hardenable by cold working.
Type 201 has similar bending, forming and drawing characteristics to Type 301 stainless steel
Type 201 can be welded by all conventional methods applied to 18 percent chromium, 8 percent nickel steels. Filler metal of the conventional chromium-nickel analyses can be used. Like other austenitic stainless steels where carbon is not controlled below 0.03%, Type 201 is susceptible to intergranular corrosion in the weld heat affected zone.
Type 201 is resistant to a wide variety of mild to moderately corrosive environments. It has corrosion resistance approaching that of Types 301and has been successfully substituted for 304 in many mild environments.
