Complete Heat Treating and Metallurgical Services
Sun Steel Treating possesses the metallurgical expertise and production capacity necessary to provide your products with the most comprehensive and environmentally sustainable heat treating solutions available.
Ionitriding®
Ionitriding® is a method of surface hardening that produces a nitrided case using the glow discharge technology to generate nitrogen ions to the surface of a metallic part for diffusion. This process is done in a vacuum vessel at low temperatures (750°-1040°F or 400°-560°C) and can be applied to any ferrous metal.
IonWear®
Our trademarked surface treatment process is both environmentally safe and sustainable, engineered to enhance your products with a high degree of resistance to both wear and corrosion.
Vacuum Hardening
Our innovative vacuum hardening solutions provide your tooling and equipment with a superior surface finish that resists oxidation. Consistent hardness results produced throughout the part. Available for a wide range of steel types.
Normalizing
Normalizing is a relatively simple metallurgical process that Sun Steel Treating uses to improve the homogenization of the grain structure in metal materials through carefully controlled heating and cooling.
Steam Treating
Steam treating achieves significant benefits for a wide range of metal parts. The process produces an oxide film on the surface of the part, thus enhancing its ability to retain lubricants.
Stress Relieving
Stress Relieving is used to reduce the residual stresses in the microstructure after machining or certain heat-treating operations to prevent distortion from occurring later.
Heat Treatment Polishing
Heat treatment polishing is designed to remove any remaining impurities from the metal and produce a mirror-like finish. Heat treatment polishing is typically used for metal items that are too difficult to polish by hand.
Annealing
Annealing is a process of treating metal by heating it and maintaining it above its recrystallization temperature. It increases the ductility and workability of steel parts.
Straightening Services
Our atmospherically controlled straightening department consists of 18 screw presses and 3 hydraulic presses with 24-, 75-, and 150-ton capacities. Methods of straightening include press, peen, flame, hammer, and vibro peening.
