Type 201 is an austenitic chromiumnickel-
manganese stainless steel that
was developed originally to conserve
nickel.

Type 201 is an austenitic chromiumnickel-manganese stainless steel that was developed originally to conserve nickel. It provides properties similar toType 301 and can be used in most applications
for Type 301. This alloy is nonmagnetic in the annealed condition, but becomes slightly magnetic when cold worked. The rate of work hardening is similar to Type 301, although Type 201 develops somewhat higher yield strength while retaining equal ductility when cold worked. Toughness at low
temperatures is excellent. Typical uses include appliances, restaurant equipment, cooking utensils, sinks, automotive trim, architectural applications such as windows and doors, railway
cars, trailers and hose clamps.The general level of corrosion resistance of Type 201 is similar to Type 301. Type 201 should perform adequately as a replacement for Type 301, except in the
most demanding environments. The scaling  resistance of Type 201 is less than
that of Type 301. Type 201 resists destructive scaling up to about 1550°F (843°C), about 100°F (56°C) less thanType 301.
