Carpenter 13-8 stainless steel can be processed under solution treatment and various age hardening conditions. stay Condition a alloy has good tool life and surface finish when the machining speed is 20% to 30% lower than those speeds. For carpenter custom 630 (17cr-4ni) or 20% to 30% lower than for stainless steel 302 and 304. The machinability after age hardening will increase with the increase of hardening temperature.

The excellent properties of 13-8 stainless steel plates are obtained through strict control of chemical composition and microstructure and special melting that can reduce impurities and minimize segregation. Compared with other iron-based materials, this alloy provides a high level of useful mechanical properties under harsh environmental conditions.
