Perform Indicator for Steel Grade 42CrMo, Chemical and Mechanical Properties and performance

[ Time:2019-02-18 Click:397 ]

Alloy Steel   Chinese GB/T 3077 Standard  Grade 42CrMo

Equivalent Grade:

EN Steel Number:  1.7223 1.7225  1.7227 1.3563

EN Steel Name: 42CrMo4

SAE Grade: 4140/4142

DIN: 41CrMo4  42CrMo4 42CrMoS4 43CrMo4

BS 970 : 708M40  708A42  709M40 En19 En19C

UNI: 41CrMo4   38CrMo4(KB)  G40 CrMo4  42CrMo4

JIS: SCM 440   SCM  440H   SNB 7   SCM 4M   SCM 4 

42CrMo steel is a ultra high strength steel which has high toughness, hardenability and bo abvious temper brittleness, low deformation rate after being quenched. Heat-treatment or QT(quenching and tempering) will bring high fragile resistance properties and impact resistance properties.

What is 42CrMoA?

42CrMo+A represent high level top quality steel. Phosphorus and sulphur composition is much lower than 42CrMo, which means more pure with less impurities. 

Our factory - Anyang Longteng Heat Treatment Material Co.,Ltd provide customer 42CrMoA-LT, which means much higher performance than GB/T 3077 standard. In this way, after heat-treatment,  product properties will be better.
