16MnCr5 is a low alloy chromium-manganese case-hardening steel known for its excellent combination of strength, toughness, and wear resistance. When carburized, it forms a hard, wear-resistant surface layer while maintaining a tough and durable core, making it suitable for high-stress applications. This unique property ensures it can withstand both surface wear and internal stress without compromising performance.

It is commonly supplied in the form of round bars and is widely used in the automotive and mechanical engineering industries for manufacturing critical components such as gears, shafts, crankshafts, connecting rods, camshafts, and other highly stressed parts.
