201 304 Stainless Steel Coils 3.0mm Cold Rolled Rust Proof
Product Description
What is type 201 stainless steel?
Type 201 is an austenitic chromium-nickel-manganese stainless steel that was developed in the 1950's due to worldwide nickel shortages. In the Type 201 composition, manganese and nitrogen are partially substituted for nickel.
Is 201 stainless steel rust proof?
Type 201 stainless steel is unique as it was created in response to soaring nickel prices. This means that it is cheaper, but it also has much lower nickel content. Without as much nickel, it is not as effective at preventing corrosion.
Specification
Type 201 stainless steel is an austenitic chromium-nickel-manganese stainless alloy. It was developed mid century to conserve nickel and it is used as an alternative to type 301 in some tempered applications. Because of 201 's relatively high yield strength in the annealed condition, use of 201 is limited. Type 201 is generally used in the tempered condition particularly for springs and fasteners. 201 Stainless will retain a comparable ductility to 301 even with the higher yield strength.
