Grade 700 Steel Performance
ISCOR 22 rails are typically made of Grade 700 steel, which can withstand repeated loads and impacts in industrial transportation environments.
Key properties are as follows:
| Grade 700 | Mechanical Property | Chemical Composition (%) |
| Yield Strength | Tensile Strength | Elongation | Hardness | C | Si | Mn | S | P |
| MPa | kg/mm² | MPa | kg/mm² | min | HB | | | | ≤ | ≤ |
| ≥ 350 | ≥ 35 | ≥ 700 | ≥ 71 | ≥ 10% | 220-260 | 0.50-0.70 | 0.15-0.35 | 0.80-1.30 | 0.04 | 0.04 |
