42 Cr Mo 4 / 1.7225

42CrMo4 material ( 1.7225 steel) is a European standard alloy steel, the delivery state of this steel is mostly tempered and quenched, it has high strength, high toughness, good hardenability , temper brittleness, high fatigue limit, good impact resistance after quenching and tempering , and good at low temperature impact toughness. This steel is suitable for the fabrication of large and medium sized plastic molds, transmission gears, rear axles, load-bearing tie rods, spring clips and oil well drill pipe joints that require a certain degree of strength and toughness.

Mechanical Properties



42CrMo4 grade steels have only limited weldability . Preheating to 200-300 ° C is highly recommended; The upper limit should not be exceeded due to the risk of deterioration of the chrome layer.

Alloy steel 42CrMo4 can be friction welded. However, measures are required to limit the formation of undesirable microstructures in the weld zone.
