Key Features & Benefits
- Superior pitting and chloride stress corrosion resistance (PREN >35)
- Balanced 50/50 austenite-ferrite microstructure for optimal strength
- Versatile for homogeneous (22Cr duplex) and heterogeneous welding
- Maintains mechanical properties in severe service environments
- Controlled heat input design prevents oxidation and microstructural defects
Applications
Perfect for welding wrought, forged, or cast 22Cr duplex stainless steels in chemical processing, oil & gas, marine, and industrial sectors. Suitable for joining 2205 duplex with other stainless steels and low-alloy materials.
Quality Assurance
Manufactured to strict AWS A5.9 standards with rigorous testing for ferrite content, chemical composition, and mechanical performance. Each spool undergoes quality inspection to ensure consistent weldability and corrosion resistance.
