Description
20MnCr5 grade steel is a case hardening steel used extensively for both carburising and carbonitriding, demonstrating reasonably high hardenability and excellent forgeability.
This grade also has excellent weldability, however care should be taken to avoid weld cracking.
Machinability is approximately 80% that of mild steel.
