Therelek is among the top gas nitriding furnace manufacturers in India, providing state-of-the-art solutions for surface hardening of steel and alloy components. Our gas nitriding furnaces deliver precise nitrogen diffusion through controlled heating and gas atmospheres, enhancing surface hardness, fatigue strength, and wear resistance without distortion. Designed for long service life and accuracy, Therelekās gas nitriding furnace systems in India are engineered to perform under demanding industrial conditions.
The process involves introducing ammonia gas at specific temperatures, where nitrogen atoms diffuse into the metal surface, creating a hard and corrosion-resistant layer. The advanced temperature and gas control systems ensure consistency across all treated parts. These furnaces are ideal for gears, shafts, crankshafts, dies, and tools used in heavy engineering, automotive, and aerospace industries.
With automated controls, safety interlocks, and efficient insulation, Therelek furnaces guarantee stable operations, low energy consumption, and repeatable metallurgical results. As trusted gas nitriding furnace suppliers in India, Therelek focuses on reliability, performance, and innovation, making our furnaces an essential part of modern industrial furnaces in India for precision heat treatment.
Ā The pit-type gas nitriding furnace is best suited for treating long shafts, rods, and cylindrical parts. It provides excellent nitrogen penetration and uniform temperature throughout the chamber. The design ensures efficient gas circulation, minimizing distortion and maximizing surface hardness, making it ideal for precision heat treatment operations.
Ā Therelekās Horizontal Gas Nitriding Furnaces with Vacuum combine the precision of vacuum technology with controlled gas nitriding. This setup minimizes oxidation, ensures better diffusion uniformity, and maintains clean surface finishes.
