20MnCr5 steel (1.7147 material) is an European standard carburized steel (case hardening steel) with high strength and toughness and good hardenability. The quenching deformation is small, the low temperature toughness and the machinability are good, but the welding performance is low. It's generally used after carburizing quenching or quenching and tempering. (For specification and data sheet, please see the tables below)
1.7147 steel is used to manufacture and reload large-section tempered parts and small-section carburized parts. It can also be used to manufacture medium and small parts with medium load and low impact, such as gears, shafts, spindles, friction wheels and gears of variable speed equipment, and the sleeve of the governor, etc.
The chemical composition of 20MnCr5 steel are displayed in the following table.
