◆ Delivery Condition
EAF+(ESR) or EAF+LF+VD+(ESR), Hot rolled or Forged, Annealed, Hardness≤255HB,
Black surface or Machined surface (Peeled, Turned, Grinded), UT 100% Passed
◆ Applications
Tool Steel Round Bar DIN 1.2436 is for making Cutting and drawing tools of high wear resistance, rolls with high dimensional stability, deep drawing tools, tools of wire, bar and tube production, cold shear blades for thin sheets.
◆ Heat Treatment
Annealing |
800 to 850°C
Slow con trolled 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. 250 HB
Stress relieving |
650 to 700°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 |
950 to 980°C
Oil, salt bath (220 to 250°C or 500 to 550°C), air plast, still air.
Holding time after temperature equalization: 15 to 30 minutes.
Obtainable hardness: 64 - 66 HRC.
Special treatment: Hardening 1020°C and tempering at 500°C.
Obtainable hardness approx. 61 HRC (e.g. if followed by nitriding).
Tempering |
Slow heating to tempering temperature immediately after hardening/time in furnace
1 hour for each 20 mm of workpiece 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.
