Chronifer Labor M-Plus is a hardenable alloyed free-cutting stainless steel for high precision parts, with a better corrosion resistance than AISI 420 F (1.4034 +S) which is manufactured in Rod, Bar and coil. For all stock and size availability contact Sales.

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.
