Material EN 10083-3 42CrMo4
42CrMo4 is an industrial material.
Used to make forgings with greater strength and cross-section than 35CrMo steel, such as large gears for locomotive traction, turbocharger transmission gears, rear shafts, high-load linkages and spring clips.
The 42CrMo4 can also be used for drilling pipe joints and fishing tools in deep Wells up to 2000m.
Implementation standard: in 10083/3-2006
Similar material: 42 chromium molybdenum
42CrMo4 Features:
It has high strength, hardenability, good toughness, small deformation during quenching, high creep strength and durability at high temperatures.
42CrMo4 steel is an improvement of the American AISI standard 4140 steel. Steel has good machinability, easy to polish, easy to bite, can be electroplated.
42CrMo4 alloy steel (bar, plate, square) is suitable for large and medium-sized plastic molds with certain requirements for strength and toughness.
weldability
Engineering steel 42CrMo4 has limited weldability. Preheating to 200-300°C is highly recommended; The upper limit should not be exceeded because of the risk of deterioration of the chromium layer.
Friction welding is possible. However, precautions must be taken to limit the formation of undesirable microstructure in the welding zone
