SKS41 alloy tool steel

SKS41 tool steel is a Japanese alloy tool steel that can be used as both cold and hot work die steel. The steel is formed by adding a certain amount of tungsten on the basis of chrome-silicon steel, because the addition of tungsten helps to preserve relatively fine grains during quenching, which makes it possible to obtain higher toughness in the tempered state. Low carbon content, high strength and toughness, good malleability, poor hardenability, the steel also has a certain degree of hardenability and high temperature strength. The steel forging embryo is usually slowly annealed and fully softened after forging, but the result is unfavorable to the surface roughness of subsequent processing.

SKS41 alloy tool steel is sensitive to decarburization during heating, and it is difficult to control the quenching deformation. After carburizing and quenching, the bearing capacity and wear resistance are better than low hardenability cold work die steel, quenching heating temperature 950℃, the hardenability and hardenability of the steel are good, so the patience and pressure resistance of the die are better.

SKS41 alloy tool steel is mostly used to manufacture tools operating under high impact loads, such as pneumatic tools, chisels, punching and cutting edge compound dies, stamping dies, cold cutting scissors and other punching and cutting tools, as well as some small hot working dies.
