STAVINOX 2209

ER 2209 is a duplex stainless steel filler wire for welding the duplex stainless steels used in pipe and plate fabrication. This ER2209 filler wire resists pitting and stress-corrosion cracking very well, particularly in environments with high chloride levels. It works with both MIG and TIG welding and helps produce a balanced weld structure with dependable mechanical strength and corrosion resistance.

Key Features and Benefits of ER2209 Welding Wire

STAVINOX 2209 is engineered for the demanding requirements of duplex stainless steel welding in industrial applications.

Its main features and benefits are:

  • High Corrosion Resistance: The weld metal stands up strongly to pitting and stress corrosion cracking, so it suits aggressive, chloride-rich environments.

  • Optimised Weld Metal Structure: Nickel is set 2 to 3 percent above the parent material, which helps keep austenite and ferrite properly balanced in the as-welded condition.

  • Strong Mechanical Properties: High yield and tensile strength support durable, long-lasting weld joints.

  • Mig And Tig Process Compatibility: STAVINOX MIG 2209 covers MIG welding and STAVINOX TIG 2209 covers TIG welding, giving flexibility for different fabrication needs.

  • Stable Arc Performance: Smooth metal transfer and consistent bead formation help improve productivity.

  • Multiple Finish Options: MIG wires come in bright, matte, and semi-bright or matte finishes to match welding preferences.

  • Wide Size Range: A choice of wire diameters serves both thin- and thick-section welding.

These qualities make ER 2209 a dependable option for duplex stainless steel fabrication.
