Free-cutting stainless steel D850
D850 is a corrosion-resistant plastic tool steel with excellent machinability and dimensional stability. It is of good dimensional stability under different temperature.Through the unique design of chemical compositions and advanced smelting process, the retained austenite of D850 in the pre-hardened state is almost zero. And through the effective addition of S element, the material obtains excellent machinability. The hardness of D850 at delivery condition is 290-330HB.
