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).
