Ductile (nodular) iron from EN-GJS-400-18 to EN-GJS-700-2, to EN 1563, for parts that need strength and elongation.
Minimum tensile strength and elongation follow from the designation.
| Grade | Min. tensile strength, MPa | Min. elongation, % |
|---|---|---|
| EN-GJS-400-18 (LT and RT variants) | 400 | 18 |
| EN-GJS-400-15 | 400 | 15 |
| EN-GJS-450-10 | 450 | 10 |
| EN-GJS-500-7 | 500 | 7 |
| EN-GJS-600-3 | 600 | 3 |
| EN-GJS-700-2 | 700 | 2 |
Industrial valves, energy, railway, mining and automotive parts that carry load or pressure.
Ductile iron is cast on automatic lines, by hand moulding and by investment casting.
They mark the impact-tested variants of EN-GJS-400-18: LT for low temperature and RT for room temperature.
Choose ductile iron when the part needs more strength and elongation than grey iron gives.
Up to 250 kg on automatic lines. Hand moulding takes heavier parts.
EN-GJL-200 and EN-GJL-250.
For the highest loads.
Series castings up to 250 kg.
