Description
The ER2209 2.0mm TIG Wire 5kg is a premium-grade duplex stainless steel TIG welding wire designed for critical applications that require excellent strength and superior corrosion resistance. ER2209 is commonly used in industries such as offshore oil and gas, desalination plants, pressure vessels, and chemical processing facilities—where weld performance under harsh conditions is non-negotiable.
This TIG wire provides high tensile strength and toughness, even in environments exposed to chlorides and extreme temperatures. Because it’s a duplex alloy, ER2209 offers both austenitic and ferritic characteristics, giving it excellent resistance to pitting, crevice corrosion, and stress corrosion cracking.
The 2.0mm diameter is ideal for precision TIG welding work on stainless steel components. It ensures stable arc performance, controlled heat input, and clean, smooth weld beads. The 5kg packaging makes it a practical choice for small- to medium-scale fabrication jobs that demand consistent quality and reduced waste.
In addition to structural integrity, this wire produces welds with low intermetallic formation, helping you maintain durability over time. It’s especially effective when joining 2205 duplex stainless steel or other similar grades, making it a go-to choice for welding specialists in highly corrosive applications.
