16MnCr5 Case Hardening Steel
16MnCr5 Case Hardening Steel is supplied for mechanical engineering and serial production applications where the grade, delivery condition, dimensional tolerance and traceability must be specified together. Erkal Haddecilik supplies cut-to-length steel from Bursa subject to stock.
Key properties
- Carburising and hardening can combine a hard surface with a tough core.
- Keep 16MnCr5 distinct from 20MnCr5; confirm chemistry, section and treatment requirements.
Typical applications
- Gears and pinions requiring a specified hardened case.
- Bushings and cams, after case-depth and core-property assessment.
Typical chemical composition / standard range
| Element | Range |
|---|---|
| C | 0,14–0,19 % |
| Si | 0,15–0,40 % |
| Mn | 1,00–1,30 % |
| Cr | 0,80–1,10 % |
| P | ≤0,025 % |
| S | ≤0,035 % |

Values may vary by product standard or variant; the material certificate is the basis for purchasing specifications.
Heat treatment guide
| Process | Temperature | Note |
|---|---|---|
| Carburizing | 880–980 °C | According to the carburizing medium/process |
| Quenching | 860–900 °C | Oil or water |
| Tempering | 150–200 °C | Air cooling |
Heat treatment values are indicative; the process specification must be established separately for the part section, furnace, cooling medium and target mechanical properties.
16MnCr5 case-hardening steel: designation and ordering
16MnCr5 and material number 1.7131 identify the EN grade. A search for case-hardening steel does not make 20MnCr5 or AISI 8620 an automatic replacement; agree the specified grade and standard before ordering.
For gears and similar carburised parts, state the required case-hardening specification, starting delivery condition, section and machining allowance.
