| Mo | 0.10 – 0.25 |
High-tensile nickel-chromium-molybdenum steel
A through-hardening alloy steel that combines high tensile strength with excellent toughness and fatigue resistance. Supplied hardened and tempered for parts under sustained high stress.
| C | 0.36 – 0.44 |
| Si | 0.10 – 0.35 |
| Mn | 0.45 – 0.70 |
| Cr | 1.00 – 1.40 |
| Ni | 1.30 – 1.70 |
| Mo | 0.20 – 0.35 |
Low-alloy carburising steel
A versatile, cost-effective carburising grade delivering good case hardness with above-average core toughness. A dependable workhorse across general engineering and automotive components.
| C | 0.18 – 0.23 |
| Si | 0.15 – 0.35 |
