What is the difference between 42CrMo steel and 42CrMo4 steel?

What is the difference between 42CrMo steel and 42CrMo4 steel?

What is the difference between 42CrMo steel and 42CrMo4 steel?

(OP)
42CrMo grade is from China GB/T 3077 standard steel material. It is a medium carbon alloy structural steel with good mechanical properties, good hardenability and wide application. In the machinery industry, 42CrMo alloy is often used to manufacture gears, connecting rods, high strength bolts and other important parts. China factory create 42CrMo follow SAE 4140 steel standard.


42CrMo4 grade is from European standard-EN10083. It is a kind of alloy steel with high hardenability, good toughness and small deformation during quenching. 42CrMo4 steel has high creep strength and endurance strength at high temperature.

RE: What is the difference between 42CrMo steel and 42CrMo4 steel?

The chemical composition available thru the link gives almost identical values for both the material.

Now you need to compare the mechanical properties like tensile stress, elongation, hardness etc. of both the steels. If the values are identical, you may go for the cheaper one.
