Heat Treatment:
Forging: 1.3505 bearing steel is forged at 1950 - 2100oF (1065 - 1150oC), and should not be forged below 1700oF (925oC.) A post-forge equalization treatment is recommended at 1375oF (745oC) for 4-6 hours followed by air cooling.
Annealing: 1.3505 bearing steel is annealed at 872°C (1600°F) followed by slowly cooling to reduce cold working or machining stress.
Hardening: 1.3505 bearing steel is hardened by cold working, or heating and quenching. It can be carburized at 913°C (1675°F) followed by quenching. It is again heated at 788°C (1450°F) followed by quenching for the second time.
Applications:
DIN1.3505 bearing steel is primarily used for the manufacture of aircraft bearings and other highly stressed parts. It has the good rolling fatigue strength required at operating temperatures less than 400oF (200oC). The grade is preferably vacuum arc re-melted to give optimum performance.
