What is 42CrMo4 steel composition

Posted:2020-12-23 10:38:45

42CrMo4 steel is also called 1.7225 steel, and it is super high strength alloy steel. 42CrMo4 steel has high hardenability and toughness and it has no temper brittleness, which owes to 42CrMo4 steel composition to a large extent.

42CrMo4 steel composition: Maximum percentage of Carbon (C) is 0. 45 percent and minimum percentage is 0.38. Maximum percentage of Manganese (Mn) is 0.9 percent and minimum percentage is 0.60. Maximum percentage of Phosphorous (P) is 0.035 percent. The details is as below.

42CrMo4 steel composition:

42CrMo4/1.7225	C	Mn	Si	P	S	Cr	Mo
	0.38-0.45	0.60-0.90	0.40 max	0.035 max	0.035 max	0.90-1.20	0.15-0.30

42CrMo4 steel will get high fatigue strength after quenching and tempering. Its impact toughness is great at low temperatures. 42CrMo4 steel is a good industry material to produce big and medium plastic molds with the demand for high strength and toughness.
