Heat Treatment
Annealing : Slowly heat to 872° C (1600° F) and then slowly cool to reduce cold working or machining stresses. Different annealing methods will give different hardness. 1.3505 Bearing steel will obtain hardness MAX 248 HB.
Quenching : Heat slowly to 816° C (1500° F) and quench in oil to obtain a hardness of 62 – 66 HRc. High temperature tempering: 650-700℃, air cooled, hardness 22-30HRC. Low temperature tempering: 150-170℃, hardness: 61-66 HRC.
Applications
