Characters:

Is similar to 35CrMo performance , because carbon and chrome content increased, so its strength and its quench-hardening ability 35CrMo, better after the fatigue strength and high temperature resistance, repeated impact ability, good impact toughness and no obvious temper brittleness, generally in piece.modified after use

 Applications

 Commonly used for manufacturing 35CrMo higher than the required strength, large parts of the important sectional dimensions, such as axis, gear, connecting rod, transmission gears, the supercharger gear, engine cylinder, spring, spring clamps, 12-2000mm oil pipe fittings, fishing tools and instead of containing nickel steel high
