Oct 08, 2018 · 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 42CrMo4 DIN 1.7225 Steel Round Bar Plate Material 42CrMo4 steel is super high strength alloy steel with high hardenability and toughness and it has no temper brittleness. And it also be called DIN 1.7225 steel. After quenching and tempering, it will get high fatigue strength. Its impact toughness is great at low temperatures.
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%.
