42CrMo/1.7225 Alloy Structural Steel
42CrMo alloy structural steel characteristics
1.Has high strength and toughness.
2.It has good processability and is widely used.
3.The hardenability is also good, there is no obvious temper brittleness, and the deformation is small during quenching.
4.After quenching and tempering treatment, it has high fatigue limit and multiple impact resistance, and has good low-temperature impact toughness.
5.It has high creep strength and durable strength at high temperatures. This steel is usually tempered and then surface quenched as a heat treatment solution.
40Cr VS 42CrMo:
40Cr is chromium-containing alloy steel, and 42CrMo is chromium-molybdenum alloy steel. 40Cr has high hardness, high strength, and good comprehensive mechanical properties, but its hardness, strength, comprehensive mechanical properties, and wear resistance are all lower than 42CrMo.
In short, the comprehensive performance of 42CrMo is better than 40Cr and has been recognized by the industry.

42CrMo alloy structural steel application scope
1.This steel is suitable for manufacturing large and medium-sized plastic molds that require certain strength and toughness;
2.Used to manufacture large-section gears and rotating shafts, engine cylinders, oil drilling tools, etc.;
3.42CrMo steel is suitable for manufacturing large and medium-sized plastic molds that require certain strength and toughness;
4.Used to manufacture forgings that require higher strength and larger quenched and tempered cross-sections than 35CrMo steel, such as large gears for locomotive traction, supercharger transmission gears, pressure vessel gears, rear axles, connecting rods with extremely high loads, and Spring clips. And this steel can be used for deep oil well drill pipe joints and fishing tools below 2000m , and can be used for bending machine molds, etc.
Sanyao Company can provide customers with customized forging (including size, hardness, eye bolt, rough machining, quenching and tempering, rough surface grinding,fine surface grinding,etc.) to meet customers' individual needs.
