Trim Rite®

UNS #S42010

Trim Rite® is a quench-hardenable martensitic stainless steel that provides a moderately high level of corrosion resistance, hardness up to Rockwell C 51, good cold formability and ease of heat treatment. Hardness capability of 420 but with superior corrosion resistance and ductility. Balanced to be fully martensitic in the hardened condition and magnetic in all conditions, the alloy can be hot worked, cold worked, machined and heat treated using the same equipment and methods used for 410 stainless steel.
