The difference between 42CrMo steel pipe and 35CrMo steel pipe

There is a slight difference in the alloy composition content of 42CrMo and 35CrMo. Generally, 42CrMo has higher carbon and chromium content, which determines that its strength and hardenability are better than 35CrMo.
Although the alloy compositions of 42CrMo and 35CrMo overlap, there are still some differences. Generally, 42CrMo has higher carbon and chromium content, which determines that its strength and hardenability are better than 35CrMo, because the general material composition is Mid position.
Mechanical properties of 35crmo 42CrMo 40Cr materials and their respective advantages and disadvantages
Characteristics and application scope of 35CrMo steel pipe:
It is an alloy structural steel with high static strength, impact toughness and high fatigue limit. It has higher hardenability than 40Cr. It has high creep strength and durable strength at high temperatures. The long-term working temperature can reach 500℃; cold It has medium plasticity during deformation and poor weldability.
Scope of application
It is used as important structural parts that work under high load, such as transmission parts of vehicles and engines; rotors, main shafts, heavy-load transmission shafts of turbine generators, and large-section parts.
42CrMo steel pipe characteristics and scope of application:
It has high strength and hardenability, good toughness, small deformation during quenching, and high creep strength and durable strength at high temperatures.
Scope of application
It is 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 and spring clips that are subject to extremely high loads. , can also be used for deep oil well drill pipe joints and fishing tools below 2000m, and can be used for bending machine molds, etc.
Furthermore, compared to 40Cr, what are the advantages of 42CrMo and 35CrMo?
It should be said that 42CrMo and 35CrMo have better hardenability than 40Cr.
The hardness of 42CrMo and 35CrMo is slightly higher.
