Puntos Clave de Venta

Rendimiento Clave

Designed to maintain optimal ferrite levels (>30-50FN) and PREN >35, this wire ensures welds resist pitting and chloride-induced stress corrosion. The balanced austenite-ferrite microstructure guarantees excellent mechanical properties, including high tensile strength and ductility, even in harsh operating conditions.

Escenarios de Aplicación

Perfect for welding 22Cr duplex stainless steels in chemical processing, offshore platforms, desalination plants, and marine equipment. Suitable for both homogeneous joints and heterogeneous welding between duplex stainless steels and other alloys, ensuring versatility across industrial sectors.

Aseguramiento de Calidad

Manufactured in our state-of-the-art facility, each spool undergoes rigorous testing to meet AWS A5.9 standards. We ensure consistent wire diameter, smooth feeding, and chemical composition accuracy, delivering reliable performance for critical welding applications.

Diferenciación

Unlike standard stainless steel wires, our ER2209 wire is optimized for duplex alloys, offering superior corrosion resistance and microstructure stability. The 15kg spool size minimizes downtime for large projects, while strict quality control ensures batch-to-batch consistency.

Preguntas Frecuentes

Q: What materials can this wire weld?
A: It welds EN 1.4462, S32205, SAF 2205, and their casting equivalents, plus heterogeneous joints with other stainless/low-alloy steels.

Q: What gas should I use?
A: Ar+2%CO?, Ar+5%CO?, or argon/helium mixtures to prevent weld oxidation.

Q: How to ensure optimal microstructure?
A: Control heat input and interpass temperature to achieve the 50/50 austenite-ferrite balance.
