Hard facts
Applications & tips
Back to overviewCase-hardened components are heat-treated steel workpieces. Here the workpiece is carburised, hardened, then tempered. This produces a hard, wear-resistant surface, while the core remains relatively soft and tough.
Case hardening is used on non-hardenable steels. Carburising with a carburising medium (e.g. gas or packing into carbon granulate) at a temperature of 850°-950°C, enriches the surface layer with carbon atoms.
