  (1) softening annealing: its purpose is mainly to decompose carbides, to reduce the hardness of Stainless Steel Welding Equal Diameter Head Pipe Cap and to improve processing performance. For spheroidal graphite cast iron, its purpose is to obtain very high fertility iron structure.

  (2) normalization treatment: the uniform distribution of mechanical properties is mainly achieved by improving or making cast iron from iron.

  (3) quenching: the main purpose is to obtain higher hardness or wear strength of Stainless Steel Welding Ellipsoidal Head Pipe Cap, and at the same time to very high surface wear resistance.

  (4) surface hardening: the main purpose is to obtain Stainless Steel Welding Ellipsoidal Head Pipe Cap surface hardening layer, and get very high surface wear resistance.

  (5) precipitation hardening: mainly for obtaining high strength of Stainless Steel Welding Ellipsoidal Head Pipe Cap, elongation does not change drastically.
