The Hollow Hydraulic Piston Rod is mainly manufactured by the advanced technology of precision cold drawing, fine grinding and high-precision polishin

The quenching of steel is to heat the steel to a temperature above the critical temperature Ac3 (hypo-eutectoid steel) or Ac1 (hypereutectoid steel),

Tempering is a heat treatment process in which a quenched metal product or part is heated to a certain temperature, and after holding for a certain pe

Annealing is a metal heat treatment process in which the metal is slowly heated to a certain temperature, kept for a sufficient time, and then cooled

Normalizing is a heat treatment that improves the toughness of steel. After heating the steel components to 30~50℃ above the Ac3 temperature, they are

The purpose of post-plating treatment is to ensure the quality of the coating and improve the protection, decoration and function of the coating. Post
