Availability & Supply Condition.
Continuously cast rounds: 25–400mm diameter. Cut lengths available from stock.
Supply condition: Continuously cast and supplied as-cast, turned or centreless ground. Predominantly pearlitic matrix for higher strength and wear resistance.
Cut to length from 1 piece — −0/+2mm standard tolerance — 2–3 day turnaround — Cutting service details ›

Mechanical Properties.
Indicative values to BS EN 1563. Properties vary by section size and matrix condition.
| Designation | Tensile Strength (N/mm²) | 0.2% Proof Stress (N/mm²) | Elongation A (%) | Hardness (HB) |
|---|---|---|---|---|
| EN-GJS-600C / EN-JS1060 | ≥600 (min) | ≥370 | ≥3 | 190–270 |
Hardness values: see our hardness conversion table to convert between HRC, HB, HV and tensile strength.
Typical Applications.
- Heavy-duty gears and pinions
- Crankshafts and drive components
- Wear-resistant rollers and guides
- High-pressure hydraulic bodies
- Dies, bushes and wear plates
- Loaded shafts and spindles
Key Benefits.
- Highest tensile strength of the stocked ductile grades
- Good wear resistance from pearlitic matrix
- Retains ductile-iron toughness over grey iron
- Surface-hardenable by flame or induction
- Strong, damping alternative to forged steel
Remarks & Guidance.
EN-GJS-600C has a predominantly pearlitic matrix, giving higher tensile strength and hardness with lower elongation than the ferritic grades. Best suited to heavily loaded, wear-resistant components where strength is prioritised over maximum ductility. Bearing and gear surfaces can be flame or induction hardened. Weldable only with care, using nickel electrodes and pre-heat. Properties vary with section size.
