The increased molybdenum content in M50NiL improves surface wear resistance. Compared to M50, M50NiL has lower carbon and higher nickel, which gives the alloy a tougher, more fracture-resistant core.
Equivalent Grades
In high-temperature service, M50NiL works as an alternative to M50 or 9310. M50 steel is typically through hardened, whereas M50NiL is carburizable to create a hard surface while maintaining a relatively soft core. Compared to 9310, M50NiL exhibits superior fatigue life in similar applications.
Heat Treatment
Heat treating and carburizing M50NiL creates a part with a hard surface case and a tougher (less brittle) core than a through hardened grade such as M50. Sullivan Steel supports customers with guidance and documentation for heat treating M50NiL to help ensure the steel meets your service requirements.
Applications
M50NiL is machinable using standard methods, including sawing, turning, drilling, cutting, and boring. It is well suited for components subject to high temperatures, where hardness and fatigue strength are both critical. In the aerospace industry, M50NiL is used for:
- Bearings
- Gears
