A485: 2017 / Standard Specification for High Hardenability Antifriction Bearing Steel

Heat Treatments

  • Normalizing followed by spheroidize annealing shall precede heating for end quenching. In heating for end quenching, the test specimens shall be held for a minimum of 30 min at 815 ± 4.5°C (1500 ± 8°F).
