What is the Difference between Type 201,304,316 Stainless Steel Plate
201 is a low nickel, high-work hardening, austenitic chromium-nickel-manganese stainless steel, 201 is a lower cost alternative to conventional Cr-Ni stainless steels such as 301 and 304. Type 201 can be substituted for Type 301 in many applications.
201 stainless steel flat rolled coil is non-magnetic in the annealed condition but becomes magnetic when cold-worked.
