TIG Filler Wire 2209 Stainless Steel – 2.4mm
Product Overview
This 2.4mm ER2209 duplex stainless steel TIG filler wire is engineered for welding duplex and super duplex stainless steel base metals where high strength and superior corrosion resistance are critical. With a balanced austenitic-ferritic microstructure, ER2209 filler wire delivers excellent mechanical properties and outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking — making it a top choice for demanding industrial applications.
Key Features
- Duplex Composition: Formulated with a controlled balance of chromium, nickel, molybdenum, and nitrogen to match the base metal's dual-phase (austenite-ferrite) structure
- High Corrosion Resistance: Ideal for chloride-rich and acidic environments, including marine and offshore applications
- Superior Strength: Offers roughly double the yield strength of standard austenitic stainless steels (e.g., 304/316)
- Smooth Feedability: Precision-drawn 2.4mm diameter ensures consistent arc stability and clean, spatter-free welds
- Excellent Weld Bead Quality: Produces smooth, uniform beads with minimal slag and easy cleanup
Typical Applications
- Pulp and paper industry equipment
- Chemical processing and storage tanks
- Offshore oil and gas platforms
- Desalination plants
- Marine and shipbuilding components
- Pressure vessels and piping systems handling corrosive media
