20MnCr5 Case Hardening Steel
20MnCr5 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
- Case-hardening grade selected for the required case and core properties.
- Do not replace 16MnCr5 automatically; check chemistry, section and the treatment specification.
Typical applications
- Transmission gears and pinions with defined case-hardening requirements.
- Drivetrain shafts and gear components assessed for section and core properties.
Heat treatment guide
| Process | Temperature | Note |
|---|---|---|
| Carburizing | approximately 860–900 °C | Depending on the process |
| Quenching | depending on the process | Oil/water selection depends on the application |
| Low-temperature tempering | depending on the application | According to target surface hardness |
The Ovako 20MnCr5 datasheet recommends 860–900 °C for carburising. This producer-specific guidance is not a universal process recipe; verify the actual material, section, furnace and target case/core properties. Ovako 20MnCr5 (2025-01-16)
Heat treatment values are indicative; the process specification must be established separately for the part section, furnace, cooling medium and target mechanical properties.
20MnCr5 case-hardening steel: designation and ordering
20MnCr5 is associated with material number 1.7147. Keep it distinct from 16MnCr5 / 1.7131: a shared case-hardening application is not proof of interchangeable chemistry or treatment response.
Send the drawing grade, required case and core conditions, section, cut length and inspection requirements; do not choose solely by a similar name.
Supply and cutting enquiries from Bursa
Erkal Haddecilik handles material and cut-to-length enquiries from Bursa/Nilüfer for projects in Türkiye. Send the grade specification, dimensions, quantity and delivery location; availability, cutting details, shipment and timing are confirmed in the quotation, not guaranteed by this page.

Technical selection note
Steel grades must not be considered exact equivalents based on similar names alone. Chemical composition, mechanical properties, product standard, delivery condition and heat treatment requirements must be verified against the certificate.
