Mechanical properties of 42CrMo4 steel: The following are some mechanical properties of 4142 steel:

The tensile strength of this grade of alloy steel is expressed in Newtons per millimeter and it must be at least 1000 N/mm2 (MPa).

The elongation characteristics of 42CrMo4 steel vary with the heat treatment process and thickness, but are usually expressed as 11%.

42CrMo4 can be welded by all fusion and resistance methods. But it cannot be welded by the oxy-acetylene welding method.

The yield strength of this grade of alloy steel is expressed in Newtons per millimeter and it must be at least 550 N/mm2 (MPa).

The weldability of 42CrMo4 high-grade steel is very low. The process of preheating base steel to 200 to 300°C is extremely complex. The temperature should not exceed this range, as it will damage the chrome layer.

Alloy grade 42CrMo4 can be welded with the help of friction. However, precautions need to be taken to prevent the growth of unwanted weakened microstructure in the welding area.

42CrMo4 has high strength and wear resistance and is widely used in many industries. High strength and toughness components for tools, automotive parts, mechanical engineering, military components, such as gears, pinion, connecting rod, mechanical engineering parts. Static and dynamically stressed components for vehicles, engines and machines. For large section parts, crankshaft, gear
