division of cast steel, performance of cast steel

Alloy Steel Casting is roughly divided into carbon steel cast steel and alloy steel cast steel. Carbon steel cast steel does not regard elements other than carbon C as effective elements (elements necessary to obtain useful properties). On the other hand, in addition to carbon C, alloy steel cast steel also adds elements such as chromium Cr, manganese Mn, molybdenum Mo, nickel Ni, and silicon Si. Add elements.

The casting performance of cast steel structural steel and special-purpose low-alloy cast steel is similar to that of carbon cast steel. Chromium and molybdenum in steel will reduce the fluidity of molten steel. Copper, manganese, nickel, etc. improve fluidity. Volume shrinkage of steel is mainly related to carbon content. The higher the carbon content, the higher the shrinkage and the less affected by the alloying elements. Manganese and vanadium, titanium, zirconium, and other elements that refine the crystal structure can reduce the tendency for pyrolysis, while chromium and molybdenum increase the tendency for pyrolysis. As alloying elements reduce thermal conductivity and increase casting stress, cast steels, especially steels containing elements such as manganese, chromium and molybdenum, are more prone to cold cracking.
