201 Stainless Steel Strip Coil

Type 201 stainless steel strip coil (UNS S 20100) is a low nickel, high-work hardening, austenitic chromium-nickel-manganese stainless steel that was developed to conserve nickel. It does not harden with heat treatment but can be work hardened to high tensile strengths. This alloy is also often polished for cosmetic applications.

201 Stainless Steel Applications:


  • Pots
  • Pans
  • Flatware
  • Counters
  • Sinks
  • Appliance components

Magnetic properties:

 201 stainless steel flat rolled coil is non-magnetic in the annealed condition but becomes magnetic when cold-worked. In some cases, 201 may be substituted for other higher nickel content alloys.


Type 201 stainless steel is formable to most shapes but will work-harden disallowing the most severe forming operations unless annealed prior to forming
