Surface heat treating steel for long-lasting performance
No matter your industry, your metal components face extreme demands. They must withstand heavy wear but stay flexible enough to resist cracking. Our surface heat treatment processes modify the outer layer of steel and create a hard, wear-resistant surface while maintaining the core’s natural flexibility.
This treatment is essential for any component that must endure repeated stress—whether it’s aircraft landing gear, an automotive crankshaft, or molds and dies in manufacturing equipment.
Carburizing steel for reliability and durability
Gas carburizing is a surface hardening process that enhances the durability of steel by diffusing carbon into the metal’s outer layer. The result is a tough, wear-resistant surface paired with a strong, flexible core—ideal for components that face repeated stress. Carburized steel parts improve wear resistance and fatigue strength, making this process a perfect fit for gears, shafts, bearings, and other high-load applications.
Carbonitriding for low-carbon steel
Carbonitriding is a surface hardening process similar to carburizing but with the addition of nitrogen alongside carbon. This makes it especially effective for low-carbon steels (such as AISI 1018), which don’t respond well to traditional carburizing.
Similar to carburizing, carbonitriding improves wear resistance and fatigue strength, delivering durable, long-lasting parts ideal for demanding applications.
Nitriding for minimal part distortion
Nitriding is a surface hardening process that improves wear resistance, fatigue strength, and corrosion resistance in steel and other ferrous alloys. This method diffuses nitrogen into the material’s surface at elevated temperatures in a controlled atmosphere. Nitriding produces minimal part distortion, making it ideal for precision components. While it can result in a slightly more brittle surface compared to carburizing or carbonitriding, nitriding offers excellent dimensional stability and surface durability.
Induction hardening for precision treatment
Induction hardening is a rapid surface hardening process for components that require precise treatment. It involves heating the surface of a part using concentrated electromagnetic induction and immediately cooling (quenching) it. This method offers exceptional control, achieving consistent results, minimal distortion, and efficient processing. It’s perfect for delicate or complex metal components where accuracy is critical.This method diffuses nitrogen into the material’s surface at elevated temperatures in a controlled atmosphere.
