304 7mm Grade TP309S，0Cr23Ni13，309S，S30908，Stainless Steel Sheet for Construction
DESCRIPTION
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.
