We use the following Ductile Iron Grades, each with their EN and ASTM equivalents:
| Grade | EN Equivalent | ASTM Equivalent | Typical Use |
|---|---|---|---|
| SG 450/10 | EN-GJS-450-10 | ASTM A536 65-45-12 | Ideal for medium-strength components and general engineering. |
| SG 500/7 | EN-GJS-500-7 | ASTM A536 70-50-05 | Suitable for construction and higher-stress mechanical parts. |
| SG 450/12 | EN-GJS-450-10 | ASTM A536 60-42-10 | Used in heavy commercial vehicles and trucking components. |
| SG 400/15 | EN-GJS-400-15 | ASTM A536 60-40-18 | Best for shock-resistance and ductility-focused applications. |
| SG 400/18 | EN-GJS-400-18 | ASTM A536 60-40-18 | Preferred in applications where flexibility and elongation are essential. |
| SG 550/6 | EN-GJS-550-6 | ASTM A536 80-55-06 | Good for parts requiring both strength and moderate ductility. |
| SG 600/3 | EN-GJS-600-3 | ASTM A536 80-60-03 | Used in high-load applications with limited elongation.s |
| SG 700/2 | EN-GJS-700-2 | ASTM A536 100-70-03 | High strength grade for performance-critical parts. |
