59403 - Avesta ER2209 Duplex Stainless TIG Rod 1.6mm (1/16") - 10lb Box

High-Performance Duplex Stainless Filler Metal

The Avesta ER2209 TIG Rod is a premium-grade filler metal specifically engineered for the welding of duplex stainless steels, such as UNS S31803 and S32205 (commonly referred to as 2205). This 1.6mm (1/16") diameter rod is formulated to produce a weld metal with a microstructure consisting of an optimal balance of austenite and ferrite. This balanced phase distribution ensures superior mechanical properties, including higher yield strength and better toughness than standard austenitic stainless steels like 304 or 316.

One of the defining characteristics of the ER2209 alloy is its exceptional resistance to stress corrosion cracking (SCC), particularly in chloride-rich environments. Additionally, the high chromium (~22%), molybdenum (~3%), and nitrogen content provide a Pitting Resistance Equivalent Number (PREN) generally exceeding 35, offering outstanding resistance to pitting and crevice corrosion. This makes the Avesta ER2209 an essential consumable for critical fabrication in industries such as offshore oil and gas, chemical processing, desalination, and pulp and paper manufacturing.

Designed for the Gas Tungsten Arc Welding (GTAW) process, this rod performs best with 100% Argon shielding gas. It delivers clean, defect-free deposits suitable for rigorous radiographic inspection. The rods are precision-manufactured to ensure consistent diameter and surface cleanliness, minimizing the risk of weld contamination. Packaged in a durable 4.54 kg (10 lb) box, the product is protected against moisture and environmental contaminants during storage and transport.
