EN9 Steel Billets
EN9 (070M55) high carbon steel. A higher carbon grade for components needing more strength and wear resistance than EN8 allows.
EN9 chemical composition
| C | 0.50 – 0.60 % |
|---|---|
| Si | 0.10 – 0.40 % |
| Mn | 0.50 – 0.80 % |
| S | 0.050 max % |
| P | 0.050 max % |
Indicative ranges from the common grade standard. The final analysis is as per the order and the heat test certificate.
Equivalent grades
070M55 (BS 970) · SAE 1055 approx. · C55 approx.
Equivalents are approximate. See the grade equivalents guide.
EN9 billets and blooms
EN9 billets and blooms are used where the part is forged and then heat treated for wear resistance.
Kesari Alloys supplies EN9 as continuous cast billets and blooms from 100 × 100 to 250 × 250 mm and 200 mm round, in lengths up to 12 metres. See the billet size chart for weight per metre.
Heat treatment: Normalised or hardened and tempered. Care is needed in welding and quenching because of the higher carbon.
Typical uses of EN9
- Heavy-duty shafts
- Agricultural and earth moving parts
- Wear parts and blades
- Springs and light-duty tools
Industries: earth moving machinery.
