GB/T 3077 50CrMo4 Alloy Steel Plate

GB/T 3077 50CrMo4 Alloy Steel Plate

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.
