16MnCr5 case hardening steel
OTAI SPECIAL STEEL is 16MnCr5 case hardening steel stockholder and supplier from China. more than 25 years of experience in 16MnCr5 steel round bar, flat bar and plate supply.
16MnCr5 (1.7131) is a low-alloy case hardening steel (carburizing steel) defined under DIN EN 10084. It is widely used for manufacturing components requiring high surface hardness and excellent core toughness. This steel is particularly suited for gears, shafts, automotive parts, and machinery components subjected to wear and dynamic loads.
16MnCr5 case hardening steel properties are as below:
Form of Supply
16MnCr5 steel, we can supply the round bar, steel flat bar, plate, hexagonal steel bar, and steel square block. Round bar can be sawn to your required lengths as one-offs or multiple cut pieces. Rectangular pieces can be sawn from flat bar or plate to your specific sizes. Ground tool steel bar can be supplied, providing a quality precision finished bar to tight tolerances.

Chemical composition
| C(％) | 0.14～0.19 | Si(％) | ≤0.40 | Mn(％) | 1.00 – 1.30 | P(％) | ≤0.025 |
| S(％) | ≤0.035 | Cr(％) | 0.80 – 1.10 |
Mechanical Properties
The mechanical properties of 16MnCr5 steel are outlined in the following table.
| Property | Value Range |
|---|---|
| Tensile Strength (Rm) | 800 – 1100 MPa |
| Yield Strength (Rp0.2) | ≥ 500 MPa (core) |
| Elongation (A5) | ≥ 10% |
| Impact Toughness (ISO-V) | ≥ 35 J (core) |
| Hardness (Surface) | 58 – 62 HRC (after case hardening) |
Heat treatment Related
| Process | Parameters |
|---|---|
| Normalizing | 870 – 900°C, air cooled |
| Carburizing | 880 – 980°C |
| Hardening | 780 – 820°C, oil quenching |
| Tempering | 150 – 200°C (for case hardened parts) |
| Case Depth | Typically 0.8 – 1.2 mm after carburizing |
After carburizing and quenching, 16MnCr5 achieves a hard, wear-resistant surface and a tough, ductile core, ideal for high-performance gear components.
