NCT is a company specializing in metal heat treatment, located at 12-42 Songsanpodo-ro 374beon-gil, Songsan-myeon, Hwaseong-si, Gyeonggi-do. Led by CEO Choi Dong-cheol, its main business areas are gas nitriding heat treatment and oxynitriding heat treatment.

Business Areas

• Gas Nitriding Heat Treatment: Gas nitriding heat treatment is a process that diffuses nitrogen into the metal surface at temperatures of 500~550°C using ammonia gas, etc., to improve hardness, wear resistance, and fatigue strength. It is effective in strengthening the surface without changing the core properties of the material.
• Oxynitriding Heat Treatment: Oxynitriding heat treatment is a surface treatment method that involves introducing an oxidizing atmosphere (steam) after nitriding to form an oxide film layer (Fe3O4) on the surface of the nitride compound layer. This enhances the mechanical properties of conventional nitriding and further improves wear resistance, corrosion resistance, and anti-seizing properties.

Products

• Gas Nitrided Products: Gas nitrided products are items where nitrogen is diffused into the surface of metal parts to enhance hardness and wear resistance. They are applied in fields requiring high durability, such as gears, aerospace components, and tools.
• Oxynitrided Products: Oxynitrided products are items that undergo an oxidation process after nitriding to form an oxide film layer on the surface, thereby enhancing corrosion resistance and anti-seizing properties. This contributes to increasing the lifespan and reliability of parts used in harsh environments.
