Low Pressure Carburizing Heat Treatment Furnaces are used specifically for adding carbon to metal surfaces and providing surface hardness. Low pressure furnaces carry out the carburizing process under low pressure, ensuring a more homogeneous and controlled carburizing process. The low-pressure environment enhances the uniform distribution of carbides, providing smoother surface hardness and durability. Low pressure furnaces are especially used in industries such as automotive, engineering, energy, and defense, for carburizing parts that require high strength, such as gears, shafts, and axles.
