50CrMo4 is one of the last grades that is classified as structural steel for thermal improvement and its only similar steel grade is 50H - not containing Molybdenum.
50CrMo4 steel with a particular composition are dedicated for vehicles and machines that require high hardness and are subject to strong bending, twisting, abrasion and wear loads.
Chemical composition (%) of steel 50CrMo4:
0.46 - 0.54
0.5 - 0.8
0.9 - 1.2
0.15 - 0.3
