303 Stainless Steel Plate and sheet

Good Machinability

Improve performance in rugged environments with 303 stainless steel plate from TCI Precision Metals. A non-magnetic, austenitic stainless steel that cannot be hardened by heat treatment, 303 stainless steel plate offers good weather resistance, toughness and forming properties. Comprised of chromium, nickel, stainless steel, and other alloys, this material type is designed to exhibit improved machinability while maintaining strong mechanical and anti-corrosion properties.  303 stainless steel plate is typically used for heavily machined parts.
