Quality Standard:

DIN 17230-1980 Ball and Roller Bearing Steels
ASTM A29 Standard Specification Steel Bars, Carbon and Alloy, Hot-Wrought, General Requirements


  • FORGING:forming temperature: 1100-850℃
  • SOFT ANNEALING: Heat to 730-760, cool slowly. This will produce a maximum Brinell hardness of 207.
  • STRESS RELIEVING: Stress relieving to remove machining stresses should be carried out by heating to approx. 600-650, holding for 1-2 hours at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.
  • HARDENING: Harden from a temperature of 780-810, 820-850 followed by water or oil quenching. Hardness after quenching is about 60 HRC.
  • TEMPERING: Tempering temperature: 150-180.


It can be used as structural steel for manufacturing of balls, rollers and needles for bearings up to 10 mm of thickness. This steel grade can be used also as cold working tool steel.
