4. 1.2738 Delivered Condition :
Hot rolled or forged, EAFor ESR material Black or machined surface, Annealed hardness: HBS≤235, Hardened hardness: HRC=28~35
5. 1.2738 characteristics: Smelted by using vacuum degassing method, so that the steel quality is more purified.
Has superior mirror polishing property.
Good etching workability and EDM spark workability.
Delivered in pre-hardened state; allowable for direct mold cutting without further heat treatment.
Distress annealing and surface nitriding treatment, with very slight change in size and hardness
6. 1.2738 Applications:
Injection die, extrusion die, blowing die etc. application to hot-plastic forming have good nitridting performance; nitriding treatment can significantly the die performance;
they also are often used in important mechanical parts.
