Characteristics

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

2. High toughness and cold and heat-fatigue resistance.

3. Excellent toughness hot fatigue resistance and certain abrasion resistance at medium temperature.

4. During air cooling, deformation and oxide skin tendency is small. Good resistance from the undermining of fusing aluminum.

 

Delivery condition

Annealing,

hardness is below 235HB

Surface: black, machined, painted and other customized.
