● Features and application:
  ABBAB 618 for the vacuum degassing processing of chromium-molybdenum alloy steel, high purity, uniform requirements for light polishing or etching
After spending a good plastic mold surface, the factory has been hardened and tempered.
      ASSAB 618 pre-hardened steel with about advantages:
      * No risk of quench cracking
      * Cost without heat treatment
      * Saves processing time required
      * Lower tool costs (without correction of distortion, only a polishing process)
      * Oxidized to improve the surface wear or hardening of the mold surface to reduce the local flame surface damage.
