Cold Drawn 4140 Alloy Steel Seamless Tube

Cold Drawn 4140 Alloy Steel Seamless Tube

cold drawn 4140 steel tube is a medium carbon, chromium-molybdenum steel with high hardenability. It is softened from the mill structure, to a pearlite structure, prior to cold drawing. This improves the ductility and can help improve machinability.
