After quenching and tempering treatment, 40Cr steel has good comprehensive mechanical properties, low temperature impact toughness, low notch 42CrMo,4140,SCM440,42CrMo4 high tensile steel bar 42CrMo , 4140, SCM440, 42CrMo4 high tensile steel bar. 42CrMo is a Chinese standard chromium-molybdenum high strength steel with good hardenability and toughness. This steel usually adopts quenching after tempering as the heat treatment solution. After tempering, it has relatively high fatigue and impact resistance and no obvious temper

A brief inroduction of 40Cr alloy structual steel SHEW-E

Jan 07, 2019 · Except quenching and tempering, 40Cr is also suitable for nitriding and high-frequency quenching. The hardenability of 40Cr steel is good, which can be reached to 28 ~ 60mm in water quenching and 15 ~ 40mm in oil quenching. When 174 ~ 229HBS, the relative machinability is 60%.
