Case-Hardened Steels

Case-hardened steels are specially engineered materials featuring a hard, wear-resistant surface layer and a tough, ductile core. These steels, typically low-carbon alloyed or non-alloyed, undergo carbon diffusion treatments to achieve hardened surfaces while preserving a resilient internal structure. This combination ensures durable yet tough performance. Key Features: • Hard outer case with tough inner core • Excellent wear resistance • More cost-effective than high-carbon steels • Widely used in gears, shafts, pulleys, and other industrial components
