ufacture hard and wear-resistant surface parts and flexible parts, such as gears and shafts. In order to increase the toughness of the core of the part,
the carbon content in the steel should be low, generally 0.12 to 0.25%, and there is also an appropriate amount of alloy elements to ensure proper hardenability. Nitrided steel also needs to add alloy elements (such as Al, Cr, Mo, etc.) that are easy to form nitrides. Carburized or carbonitrided steel, after carburizing or carbonitriding at 850～950℃, quenched and used under low-temperature tempering (about 200℃). The nitrided steel is directly treated by nitriding
(480～580℃), and it is no longer quenched and tempered.
