UNS S32205 / 1.4462 Duplex Stainless Steel Round Bar

2205 duplex stainless steel round bar is a non-martensitic alloy with dual-phase austenite and ferrite structure. It is well-known for high strength and excellent chloride corrosion resistance, widely used in marine, petrochemical, desalination and FGD industries.

1. Material Grade: UNS S32205 / 1.4462, low carbon duplex stainless steel
2. Size Range: Diameter 6mm–200mm, standard length or custom cut-to-length
3. Key Properties: High yield strength, great resistance to pitting & stress corrosion cracking, good weldability

Application Cases of 2205 Duplex Stainless Steel Round Bar

1. Oil & Gas Offshore Project 2205 round bars are machined into pump shafts, valve stems and high-strength fasteners for offshore platforms. It resists chloride and H₂S stress corrosion cracking, meeting NACE standard for sour service.
2. Seawater Desalination Plant Used for high-pressure pump components and valve parts in SWRO desalination systems. It withstands high chloride brine, extending service life compared with 316L.
3. Pulp & Paper Bleaching Workshop Fabricated into agitator shafts and equipment bolts. It performs well in mixed acid and chloride bleaching liquor, avoiding pitting corrosion.
4. Marine & Coastal Engineering Processed into propeller shafts, mooring bolts and deck fittings for ships and coastal structures. High yield strength reduces component weight while resisting seawater corrosion.
