Product Parameters

Product introduction

42CrMo steel belongs to ultra-high strength steel,

Properties of 42CrMo alloy steel:

1. It has high strength and toughness and good hardenability. 2. No obvious temper brittleness, small deformation during quenching, 3. After quenching and tempering treatment, it has higher fatigue limit and multiple impact resistance. 4. Good impact toughness at low temperature and high creep strength and endurance strength at high temperature.

42CrMo alloy steel uses:

It is used to manufacture important parts with higher requirements or larger cross-sectional dimensions than 35CrMo steel, such as large gears for locomotive traction, supercharger transmission gears, rear axles, gearbox gears, engine cylinders, connecting rods under heavy load, spring clips, drill pipe joints and fishing tools for deep oil wells of 1200~2000m, etc. The steel is also suitable for manufacturing large and medium-sized plastic molds that require certain strength and toughness.
