Vacuum type gas nitriding furnace companies

The Gas Nitriding Furnaces engineered by S R Thermal are designed to execute the nitriding and nitrocarburizing processes with extreme atmospheric control. Operating typically between 500°C and 600°C, these furnaces introduce ammonia gas into a sealed retort, where it dissociates to allow nitrogen atoms to penetrate the surface of the metal. S R Thermal’s designs are particularly praised for their Even Temperature Distribution, which is critical for preventing the distortion of precision parts like gears, crankshafts, and extrusion dies. By utilizing high-quality Kanthal A1 heating elements and Fibrothol lining work, their furnaces minimize heat loss, significantly reducing the energy cost per batch.

Safety and repeatability are the hallmarks of S R Thermal’s engineering. Their systems often feature Thyristor-based power control and advanced gas flow meters to maintain a stable dissociation rate. This precision ensures that the "white layer" or compound zone of the nitrided part is kept within the exact microns required by the client’s specifications. With material loading capacities ranging from 400 kg to over 1000 kg, their furnaces cater to both small-scale workshops and large-scale industrial plants. Choosing an S R Thermal furnace means opting for a system that offers high fatigue strength, enhanced corrosion resistance, and the dimensional stability required for high-value engineering components in today's global supply chain.
