Delivery Condition

EAF+(ESR) or EAF+LF+VD+(ESR), Hot rolled or Forged, Annealed, Hardness≤285HB, Black surface or Machined surface (Peeled, Turned, Grinded), UT 100% Passed

Annealing

610 to 650°C Slow controlled cooling in furnace at a rate of 10 to 20°C/hr down to approx. 600°C, further cooling in air. Hardness after annealing: max. 285 HB. Stress relieving Approx. 650°C Slow cooling in furnace; intended to relieve stresses set up by extensive machining, or incomplex shapes. After through heating, hold in neutral atmosphere for 1 to 2 hours. Hardening 840 to 870°C Oil, salt bath (300 to 400°C), air. Holding time after temperature equalization: 15 to 30 minutes. Obtainable hardness: 53 - 57 HRC in air. 54 - 58 HRC in oil or salt bath. Tempering Slow heating to tempering temperature immediately after hardening/time in furnace 1 hour for each 20 mm of work piece thickness, but at least 2 hours/cooling in air. For average hardness figures to be obtained, please refer to the tempering chart. For certain cases we recommend to reduce tempering temperature and increase holding time.
