TD treatment: pre-polishing→preheating→TD treatment (960°-1000°)→oil Quenching→tempering→washing→drying→post-polishing→quality inspection (film thickness/base material hardness/deformation)→shipping

Definition: The surface is formed with high hardness and high corrosion resistance vanadium carbides, which can achieve a long life effect.


 Features: 

  ①Good corrosion resistance;

  ②It can also be used as a quenching treatment of base material;

  ③It can effectively improve the hot glue and adhesion phenomenon;

  ④The high-hardness surface coating can ensure high-quality wear resistance.


 Features:

  ①The tolerance can be controlled within ±3/100 under the conditions of previous heat treatment;

  ②The treatment layer will not appear sand holes, cracks and other defects, and has high adhesion;  

  ③After TD treatment, the surface will be polished.  

  Applicable steel types:

  Steel grades with quenching temperature of 1030 degrees

  such as DC11, DC53, DHA1, etc.
