Our Decarb Annealing Furnaces are designed to process steel components by heating them to temperatures ranging from 800°C to 950°C in a controlled neutral or reducing atmosphere, promoting the removal of excess carbon from the surface to improve the material's surface quality and prepare it for further processes such as plating, welding, and machining, making it ideal for applications in industries like automotive, aerospace, and manufacturing for components such as exhaust valves, shafts, and gears, where surface integrity and uniform material properties are crucial for performance and durability.


At HIGHTEMP, our Isothermal Annealing Furnaces are engineered to process materials such as carbon steels (e.g., AISI 1040, 1050), alloy steels (e.g., 4140, 4340), cast iron (e.g., grey and ductile iron), and stainless steels (e.g., 304, 316) by heating them to temperatures between 700°C and 900°C, holding them at an isothermal phase to achieve uniform microstructures, and cooling them in a controlled manner. This process reduces hardness, enhances machinability, and improves mechanical properties for components such as gears, shafts, bearings, and engine blocks, meeting the high standards of the automotive, aerospace, and manufacturing industries.


Our Blueing Furnaces are designed to provide a protective, corrosion-resistant oxide layer on steel components by heating them to temperatures between 250°C to 350°C in a controlled atmosphere, followed by a chemical treatment to create a uniform, visually appealing finish, making them ideal for enhancing the durability and aesthetic appeal of components in industries such as automotive (brake components, gears, exhaust parts), aerospace (fasteners, bolts, shafts), and general manufacturing (tools, machine parts), with materials ranging from carbon steels to alloy steels and stainless steels, all while offering excellent corrosion resistance, increased wear resistance, and a consistent, high-quality finish for large-scale production.
