Shin Kwang Metal Heat Treatment Industry Co., Ltd.

Partial Induction Annealing

Mon, 06 Jul 2020 15:47:25 +0800

For parts after carburizing and softening, partial softening is applied to obtain better extensibility. Use high-frequency induction heating and then cooling to achieve partial softening and meet the requirements on the workpiece。

Salt Bath Heat Treatment

Mon, 06 Jul 2020 15:47:14 +0800

After heating, the workpiece is directly quenched in a salt bath to obtain toughened iron groups as in Austempering effect, and obtain better mechanical properties in terms of fatigue。

Steam Treatment

Mon, 06 Jul 2020 15:47:05 +0800

For parts after hardening treatment, a black iron oxide film is produced on the surface of the workpiece by water vapor in the furnace, which improves corrosion resistance of the parts’ surface and achieves an aesthetic outlook。

Vacuum Soft Nitriding

Mon, 06 Jul 2020 15:46:56 +0800

The workpiece to be nitrided is heated ih NH3+CO2+N2 gas in a vacuum furnace at a lower temperature to reduce deformation and obtain high surface hardness。

Stainless Steel Heat Treatment

Mon, 06 Jul 2020 15:46:46 +0800

Perform solution heat treatment for series 3 - Austenite stainless steel and hardening heat treatment on series 4 - Martensite stainless steel to improve their mechanical properties。

Aging

Mon, 06 Jul 2020 15:46:36 +0800

Perform on aluminum alloy products series 2, 6, 7 of materials solution quenching treatment and then aging precipitation to obtain the required mechanical properties。

Solution

Mon, 06 Jul 2020 15:46:26 +0800

Perform on aluminum alloy products 2, 6, 7 series of materials solution quenching treatment and then aging precipitation to obtain the required mechanical properties。

Vacuum Heat Treatment

Mon, 06 Jul 2020 15:46:15 +0800

After the workpiece is heat-treated and hardened in the vacuum furnace, a shiny surface can be obtained. This is suitable for workpieces that require a higher treatment temperature。

Carbonitriding Treatment

Mon, 06 Jul 2020 15:46:05 +0800

For small parts and parts prone to deformation, perform carbonitriding hardening treatment at lower temperature to reduce quenching deformation and obtain higher surface hardness。

Normalizing

Mon, 06 Jul 2020 15:45:55 +0800

Mechanical parts through hot forging or casting processes will have grain coarsening and more residual stress. After normalization, grains are refined and processing stress is eliminated to obtain better mechanical properties。
