WS 1.4197 Stainless Steel

Hardenable alloyed free-cutting stainless steel for high precision parts, with a better corrosion resistance than AISI 420 F (1.4034 +S)

 

Material Properties

This product is a compromise between good machinability (S-Content), high wear resistance (Cr-Ni-Mo content) and possibility for hardening (C-Content).  Chronifer Labor M-Plus resists to corrosion after tempering and a forced polishing of the parts.
