| FG 250 | 250 | 180–240 | EN-GJL-250 | Pulleys, pillow blocks, gear blanks |
| FG 260 | 260 | 180–230 | ≈ EN-GJL-250 | Brake parts, machine components |
| FG 300 | 300 | 180–250 | EN-GJL-300 | High-strength, wear-resistant parts |
SG / ductile iron IS 1865
| Grade | Tensile min (MPa) | 0.2% proof min (MPa) | Elongation min (%) | Typical hardness (HB) | Matrix | Equivalent |
|---|---|---|---|---|---|---|
| SG 400/15 | 400 | 250 | 15 | 130–180 | Ferritic | EN-GJS-400-15 |
| SG 450/10 | 450 | 310 | 10 | 160–210 | Ferritic | EN-GJS-450-10 |
| SG 500/7 | 500 | 320 | 7 | 170–230 | Ferritic-pearlitic | EN-GJS-500-7 |
| SG 600/3 | 600 | 370 | 3 | 190–270 | Pearlitic-ferritic | EN-GJS-600-3 |
Values are typical, measured on separately cast test bars. Final properties depend on section thickness and the agreed specification.
