Delivery Condition

EAF+LF+VD+(ESR), Hot rolled or Forged, Spheroidizing Annealed, EFS, Hardness≤235HB,

Unmachined or Machined (Peeled, Turned, Milled, Grinded), UT 100% Passed

 

Characteristics

1. Air cooling hardened hot work tool steel, most widely used.

2. High toughness Good cold & thermal fatigue resistance.

3. Small distortion, deformation and oxide skin after heat treatment during air cooling.

4. Good resistance from the undermining of fusing Aluminum.

 

Applications

1. For making aluminum and copper alloy die casting mold when die cavity temperature is below 600°C

2. For making forging die, forging press mold, mold hammer block for fine forging machine uses.

 

Forging Technique

Heat Temperature	Start Forging Temperature	Finish Forging Temperature	Cooling Method
1120-1150 °C	1050-1100 °C	900-850 °C	Pit or Sand Cooling

 

Heat Treatment

Annealing

750 to 800°C (1382 to 1472°F)

Slow controlled cooling in furnace at a rate of 10 to 20°C/hr (50 to 68°F/hr) down to

approx. 600°C (1112°F), further cooling in air.

Hardness after annealing: max. 235 HB.

           

Stress relieving

600 to 650°C (1112 to 1202°F)

Slow cooling in furnace; intended to relieve stresses set up by extensive machining, or in complex shapes.

After through heating, hold in neutral atmosphere for 1 - 2 hours.

 

Hardening

1020 to 1080°C (1868 to 1976°F)

Oil, salt bath (500 - 550°C / 932-1022°F), air

Holding time after temperature equalization: 15 to 30 minutes.

Obtainable hardness:

52 - 56 HRC in oil or salt bath,

50 - 54 HRC in air.

 

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.

It is recommended to temper at least twice.

A third tempering cycle for the purpose of stress relieving may be advantageous.

1st tempering approx. 30°C (86°F) above maximum secondary hardness.

2nd tempering to desired working hardness.

The tempering chart shows average tempered hardness values.

3rd for stress relieving at a temperature 30 - 50°C (86 to 122°F) be low highest

tempering temperature.
