Why Choose 2205 Duplex Stainless Steel (1.4462)
Duplex stainless steel 2205 (EN 1.4462) combines the advantages of austenitic and ferritic structures, offering:
- High yield and tensile strength
- Excellent resistance to chloride stress corrosion cracking
- Superior pitting and crevice corrosion resistance
- Reduced wall thickness requirements compared to austenitic grades
These properties make duplex stainless steel pipe fittings ideal for industrial pipelines operating under severe conditions.
