42CrMo4 steel bar – 42CrMo4 Steel Plate Material | OTAI
What is 42CrMo4 steel
42CrMo4 alloy steel is a chromium molybdenum alloy steel specification widely used in general purpose high tensile steel for components. For example, axles, shafts, bolts, gears, and other applications.
Similar to alloy grade AISI 4130 chrome moly alloy steel but with slightly higher carbon content.
The higher carbon content of 42CrMo4 steel gives greater strength and heat treatment capabilities in comparison to AISI / ASTM 4130 alloy steel.
However, it does have inferior weldability characteristics.

Customer’s story
We would like to share a real case of our customer with you. James from Canada send us an inquiry about the 42CrMo4 steel bar, which required a lot of specifications and a small quantity. James asked many suppliers who were unwilling to cooperate and finally found us. We are the source manufacturer so that we can meet the needs of customers to customize the specifications of goods. Then James placed the order successfully. After receiving the goods, he said that he would seek our cooperation for a long time. (42CrMo4 steel supplier)
FAQ
What is 42CrMo4 steel used for?
It can be used for manufacturing forgings with higher strength and larger tempering cross-section than 35CrMo steel, such as big gear for locomotive traction, supercharger drive gear, rear axle, connecting rod, and spring clamp with great load and etc.
What is 42CrMo4 QT?
As a quality alloy steel grade 42CrMo4 is commonly supplied quenched and tempered (QT) which offers good high tensile properties. It is characterized by its good ductility and shock-resistant properties that combine with good wear resistance.
Is 42CrMo4 steel stainless steel?
NO. it’s alloy steel.
What is the hardness of 42CrMo4?
It is offered in the cold finished annealed condition. Typical hardness is Rockwell “C” 19/24. Typical tensile strength 114,000 PSI. Its wear-resistant properties far exceed that of “cold roll” steels.
Is 42CrMo4 good for forging?
42CrMo4 has high strength, hardenability, good toughness, small deformation during quenching, high creep strength, and long-lasting strength at temperature.
