Carburizing is a surface hardening process that introduces carbon into the surface layer of low-carbon steel at high temperatures. This method increases surface hardness while maintaining a soft and ductile core, making it ideal for components subjected to high surface wear and stress. After carburizing, the component is usually quenched to lock in the hardness. It is commonly used for gears, shafts, and wear-resistant parts in the automotive and industrial sectors.
