MATERIAL DESCRIPTION

 

42CrMo4 +QT Steel (1.7225 Material)

42CrMo4 material (1.7225 steel) is an European standard alloy steel, the delivery condition 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 low temperature impact toughness. This steel is suitable for the manufacture of large and medium-sized plastic molds requiring a certain degree of strength and toughness, transmission gears, rear axles, load-carrying connecting rods, spring clips and oil deep well drill pipe joints.

42CrMo4+QT means this material is in the quenched and tempered condition (+QT).
