59446 - Avesta ER2209 Duplex Stainless TIG Rod 1/8" (3.2mm) - 10lb Box

Premium Duplex Stainless Steel Welding Rods

The Avesta ER2209 TIG Rod (3.2mm / 1/8") is a high-performance filler metal specifically engineered for welding duplex stainless steels, such as UNS S31803 and S32205 (commonly known as 2205). This consumable is formulated to produce a weld deposit with an austenitic-ferritic microstructure, ensuring that the mechanical properties and corrosion resistance of the joint match or exceed those of the base material. It is an essential consumable for industries operating in aggressive environments where standard austenitic stainless steels may fail.

One of the primary advantages of the ER2209 grade is its exceptional resistance to chloride-induced stress corrosion cracking (SCC) and pitting corrosion. This makes it the standard choice for fabricating pipework, pressure vessels, and structural components in the offshore oil and gas, chemical processing, and pulp and paper industries. The 3.2mm diameter is particularly well-suited for filling thicker wall sections and multi-pass welding applications where higher deposition rates are required without compromising heat input controls.

Avesta, a brand under Voestalpine Böhler Welding, is renowned for its strict quality control and metallurgical expertise. These rods are manufactured to meet rigorous AWS A5.9 and EN ISO 14343-A standards, ensuring consistent chemistry and feedability. The rods are supplied in a 4.54 kg (10 lb) box, designed to protect the filler metal from contamination and moisture during storage and transport. When used with 100% Argon shielding gas, welders can expect a stable arc, minimal spatter, and a clean, high-quality finish.

Key Industrial Applications

• Offshore & Marine: Process piping and structural components on oil platforms.
• Chemical Processing: Tanks and vessels handling corrosive acids and chlorides.
• Desalination Plants: High-pressure piping systems requiring superior pitting resistance.
