1. Engineered Excellence: The Science Behind S32205
YSAlloy’s duplex stainless steel S32205 features a 50/50 austenite-ferrite microstructure, achieving:
2× the yield strength of 316L stainless steel (550 MPa vs. 250 MPa)
PREN 38-42 for chlorine resistance (ASTM G48 Method A)
-50°C to 300°C operational range without embrittlement
Key Properties:
| Property | S32205 | 316L | Carbon Steel |
|---|---|---|---|
| Corrosion Rate | 0.001 mm/yr (seawater) | 0.03 mm/yr | 0.5 mm/yr (coated) |
| Thermal Conductivity | 15 W/m·K | 16 W/m·K | 50 W/m·K |
| Lifecycle Cost | $0.12/kg-year | $0.25/kg-year | $0.40/kg-year |
