case-hardening-steel-20MnCr5

16MnCr5 is a low alloy chromium-manganese case-hardening steel that offers exceptional mechanical properties, making it highly suitable for a wide range of engineering and industrial applications. This steel is known for its ability to undergo carburization, a process that creates a hard, wear-resistant outer case while maintaining a tough and durable core. This unique combination of a hard surface and a resilient core ensures that components made from 16MnCr5 can withstand heavy loads, surface wear, and fatigue under demanding operating conditions.
