301 Stainless Steel Strip

301 stainless strip, ASTM-A-666, is slightly lower in chromium and nickel content than Type 302. The lower nickel content causes Type 301 to work harden more rapidly and retain greater ductility than the same temper of Type 302. Gibbs Interwire stocks 301 Stainless Strip in gauges from 0.0019″ to 0.050″ precision slit to widths from 0.024″ to 12″. Type 301 is available in a variety of tempers.  View Stock Items
