Carburized steel usually refers to steel that needs to be carburized, quenched, and tempered at low temperatures before use. It is generally low carbon high-quality carbon structural steel and alloy structural steel, also known as carbon carburized steel and alloy carburized steel, respectively. Its composition is characterized by a low carbon content, typically 0.1% to 0.25%; The main alloy elements include Ni, Cr, Mn, etc., and the auxiliary alloy elements include W, Mo, V, Ti, etc. Alloyed carburized steel has high hardenability. Many machine parts, such as the gearbox gears of automobiles and tractors, cams, piston pins, and some measuring tools on internal combustion engines, are made of carburized steel.
