Types of Duplex S32205 (F60) Square Bars
Aurum Overseas supplies Duplex Steel S32205 (F60) square bars in precision bright and heavy forged conditions for high-strength and corrosion-resistant industrial applications.
Duplex S32205 / F60 Bright Square Bars
Duplex S32205 / F60 Forged Square Bars
Key Advantages
Guaranteed PREN ≥ 35
Higher controlled minimum levels of chromium, molybdenum, and nitrogen provide strict protection against localized chloride pitting.
450 MPa Minimum Yield Strength
Allows engineers to down-gauge structural section thicknesses compared to 300-series stainless steel profiles.
Superior Intergranular Resistance
Controlled chemistry prevents chromium carbide precipitation at grain boundaries during hot working and welding.
High Resistance to Stress Cracking
Ferritic-austenitic phase balance stops micro-crack propagation in warm marine atmospheres.
Key Applications
| Industry Sector | Component Type | Primary Application Advantage |
|---|---|---|
| Offshore Oil & Gas | Downhole valve shafts, Christmas tree blocks | Resists sour gas (H2S) environment cracking and deepwater pressure loads. |
| Desalination Systems | High-pressure reverse osmosis pump frames | Eliminates localized crevice corrosion under high-velocity brine exposure. |
| Chemical Engineering | Reactor agitators, acid column support bars | Maintains structural integrity in hot organic and inorganic acid flows. |
| Marine Propulsion | Rudder stocks, shaft couplings, tie rods | Prevents marine fatigue cracking under heavy ocean wave loading. |
