Grade Brief
Kuber Multimetals LLP – Trusted manufacturer, stockist & exporter of 20MnCr5 with assured quality testing (Impact, Mechanical, Chemical, Bend Tests) and global delivery.
20MnCr5 is a low-alloyed engineering case-hardening steel designed for components requiring core tensile strength of 1000–1300 N/mm², combined with high surface hardness and excellent wear resistance after case hardening. It offers a tough, shock-resistant core with a hard, wear-resistant surface—making it suitable for critical mechanical applications.
Key Properties
- Case Hardening Ability: It can be carburised and heat-treated to achieve a hard surface layer with a tough, ductile core.
- Wear Resistance: High surface hardness after carburisation ensures long service life in heavy-duty applications.
- Machinability: It can be cut, drilled, and machined with relative ease in its annealed state.
- Weldability: Suitable for welding, with proper preheating and post-weld heat treatment recommended.
- Strength: Core tensile strength in the range of 1000 – 1300 N/mm².
