Directory of stainless steel grades

AISI 416Se is a martensitic stainless steel that, due to the selenium (Se) and sulfur (S) content, provides better machinability than other similar stainless steels. However, this inclusion reduces the weldability, formability and corrosion resistance of this grade to a level lower than that of AISI 410.

MagnaCut is a unique powder metallurgical stainless tool steel whose design eliminates chromium carbide in the heat-treated microstructure. The superior combination of strength and wear resistance is achieved by containing only small, highly hard vanadium and niobium carbides, giving CPM MagnaCut properties similar to non-stainless steel CPM 4V.
