20MnCr5\/1.7147 Alloy Steel<\/h4>\n

20MnCr5 steel (1.7147 material)\u00a0is 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\u2019s generally used after carburizing quenching or quenching and tempering.<\/p>\n
