NC310YW Steel

For High Fatigue Stress Applications

A highly suitable engineering material for high mechanical & fatigue stress resistance.


In motorsport, such applications include gears, torsion bars, transmission shafts, axle shafts and driveshafts for Formula 1 racing cars.

Benefits:

NC310YW is also known as 40SiNiCrMoV10 and benefits from high strength, and the alloy's ultimate tensile strength (UTS) is 10% higher when compared to 300M steel. Carburising the alloy reduces the susceptibility of particular components vulnerable to contact friction. Carburised parts can be surface coated due to the alloy's high tempering temperature (300° C).

Cost Effectiveness:

NC310YW is highly cost-effective when compared to maraging steels. The alloy also offers excellent fatigue resistance when compared to precipitation-hardened steel. Our product provides excellent elevated temperature performance and very high strength.

Motorsport Applications:

Axle shafts, torsion bars, gears and driveshafts are highly suitable applications due to NC310YW's ultimate tensile strength and resistance to contact friction. The alloy also finds use in the production of gears.
