Product Description
20CrMnTi gear steel is a low-carbon steel with a carbon content of 0.17% - 0.24%. It is often used for manufacturing transmission gears in automobiles. It is a medium hardenability carburized carbon steel medium Cr Mn Ti steel. Its hardenability is high. Under the condition of ensuring the hardenability, it has high strength and toughness, especially high low temperature impact toughness. 20CrMnTi surface carburizing and hardening treatment steel has good workability, small special processing deformation, and good fatigue resistance | 20CrMnTi 5115 SMnC420H 5120 20MnCr5 1.7147 1.8401 | |||||||||

1.Characteristics and application: After quenching and low temperature tempering, good comprehensive mechanical properties and low temperature impact toughness can be obtained. It has good wear resistance and bending strength after carburizing. The heat treatment process is simple, and the deformation of parts is small, but there is temper brittleness during high temperature tempering. Good hot working and machinability, medium weldability. It is generally used for carburizing steel, and can also be used after quenching and tempering.
2. Carburized steel with a wide range of applications is used to manufacture important parts of automobiles and tractors with a mid section size of less than 30mm, which bear medium or heavy loads at high speed, as well as impact and wear, such as gears, gear shafts, cross shafts, gear rings, main shafts supported by sliding bearings, worms, tooth clutches, bolts, studs, etc; It can also be used instead of 20SiMn2MoVB steel
