Stainless Steel Castings
Corrosion, cavitation and high-purity service — up to 60 tons per piece.
Martensitic, austenitic and duplex stainless castings for hydropower runners, pump components, valve internals and chemical equipment, poured from AOD-quality refined heats.
| Grade | Standard / Equivalent | Tensile | Yield | Typical Applications |
|---|---|---|---|---|
| ZG06Cr13Ni4Mo | ≈ ASTM A743 CA6NM | ≥750 MPa | ≥550 MPa | Turbine runners, valve discs |
| CF8 / CF8M | ASTM A743 (304/316 cast) | ≥485 MPa | ≥205 MPa | Pump casings, fittings |
| Duplex 4A/5A | ASTM A890 | ≥620 MPa | ≥415 MPa | Seawater, chloride service |
Stainless heats receive argon protection and strict carbon control; solution annealing or quench-and-temper cycles are tailored per grade with full metallographic verification of microstructure.
Surface finishing options include pickling and passivation, and ferrite content measurement is provided for duplex grades.
