Production
Delivery Condition
EAF+LF+VD+(ESR), Hot rolled or Forged, Annealed, Hardness≤285HB, Unmachined or Machined
surface (Peeled, Turned, Grinded), UT 100% Passed
Characteristics
1. Cold work tool steel with high thoughness and full hardenability, also large dimensions.
2. High impact strength and compressive strength.
3. For oil and air hardening.
4. Good polishability.
Applications
For
making the highly stressed coining tools, cutlery dies, hobbing tools,
cold shear blades for heavy gauge material, plastic moulds.
Heat Treatment
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.
Production
Tempering
Slow
heating to tempering temperature immediately after hardening/time in
furnace 1hour for each 20 mm of work piece thickness, but at least 2
hours/cooling in air. For certain cases we recommend to reduce tempering
temperature and increase holding time.
