42CrMo4 +QT Steel Material Description

42CrMo4 material (1.7225 steel) is a European standard alloy steel, typically delivered in tempered and quenched condition. It features high strength, high toughness, excellent hardenability, resistance to temper brittleness, high fatigue limit, good impact resistance after quenching and tempering, and superior low-temperature impact toughness.

This steel is ideal for manufacturing large and medium-sized plastic molds requiring strength and toughness, transmission gears, rear axles, load-carrying connecting rods, spring clips, and oil deep well drill pipe joints.

42CrMo4+QT indicates the material is in quenched and tempered condition.
