◆ Delivery Condition

EAF+(ESR) or EAF+LF+VD+(ESR), Hot rolled or Forged, Annealed, Hardness≤285HB,

Black surface or Machined surface, 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.


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 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.
