What We Do


Metal heat treatment process that slowly heats the metal to a certain temperature and keeps it for a sufficient time and then cools it at an appropriate speed to reduce the hardness and improve the machinability, reduce residual stress, stabilize the size and reduce deformation. Refine material grains and eliminate organizational defects.

  • Reduce Hardness

  • Improve Machinability,

  • Reduce Residual Stress,

  • Reduce Deformation.

  • Eliminate Organizational Defects.


The heat treatment process that acts on the metal surface is widely used in low-carbon steel and low-alloy steel. As for the activated carburizing medium, it is heated to 900-950°C to obtain a high-carbon surface after heat preservation.

  • Improve surface hardness

  • Improve material wear resistance

  • Improve material fatigue strength

  • Keep low carbon steel strong and tough


This is a heat treatment, which follows a quenching hardening heat treatment. Tempering will increase the toughness of the hardened metal.

  • Small deformation

  • High-efficiency quenching process

  • Energy saving

  • Low pollution quenching process

  • Surface activation and clean


Our quenching heat treatments will result in a guaranteed improvement of the mechanical properties of your products, as well as an increase in their level of toughness—making these items more durable. Steel parts often require a specific form of heat treatment to obtain an increase in hardness and strength.

  • Improve surface hardness

  • Improve material wear resistance

  • Improve material fatigue strength

  • Keep low carbon steel strong and tough


Induction current is generated on the surface of metal parts, which rapidly heats the surface of the parts and quenches them quickly. Generally, a hollow copper tube coil of intermediate frequency or high-frequency alternating current is used to generate an alternating magnetic field and heat it quickly. The temperature can reach 800-1000°C in a few seconds to change the surface hardness of metal parts.

  • Fast heating speed and high efficiency

  • Low brittleness and high fatigue

  • Not easy to oxidize

  • Deeper hardened layer

Stress relief is a term commonly used to refer to Post Weld Heat Treatment; however, it should always be qualified further, as most heat treatments have the effect of reducing stresses.

  • Less chance of deformation or cracking in future heat treatments.

  • Easier machining of metals after heat treatment.

  • High performance in final application, thanks to lack of internal stress points.

  • Resistance to volatile environments.
