Industrial Furnace Solutions

We manufacture high-precision Gas Nitriding Furnaces with Retort engineered for controlled diffusion of nitrogen into steel components. These furnaces deliver superior case depth accuracy, hardness uniformity, and clean processing conditions while maintaining extremely low distortion.

Equipped with a sealed alloy retort and fully automated atmosphere control, our gas nitriding systems ensure repeatable metallurgical results for high-performance mechanical components.

Product Information


Gas Nitriding Furnace with Retort is a specialized heat-treatment system used for surface hardening, where nitrogen is diffused into the surface of steels, alloy steels, and tool steels.


The furnace operates at 500°C – 580°C, and the sealed retort ensures a clean, oxygen-free atmosphere for precise nitrogen control.


TThe system is ideal for components that must retain core toughness while achieving a hard, wear-resistant surface layer.
These furnaces are essential for industries requiring clean, uniform, and high-volume heat-treatment cycles.

Applications


  • Gears, crankshafts, camshafts
  • Tool steels, dies, and molds
  • Aerospace components
  • Hydraulic pistons and sleeves
  • Extrusion screws and barrels
  • Shafts, pins, valves, and spindles
  • Bearings, rollers, and precision wear parts
  • Fasteners and high-strength hardware
