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.
