Technical characteristics

Chemical composition of steel 40KH9S2 determined by GOST 5632−72, Alloy refers to the martensitic class. smelted in an open arc furnace. It is composed of chromium, Nickel, molybdenum, titanium, manganese, copper, carbon 0.4%, phosphorus, sulfur in hundredths of a percent. Alloying has a multifaceted effect on the quality of the steel. Chromium increases the hardness, corrosion resistance. The Nickel gives the alloy ductility; resistance to shock load. The proportion of manganese is above 1% increases the hardness, toughness, durability. Titanium increases the stability, corrosion resistance; Copper increases the ductility, prevents rusting.
