Stainless Steel Solid TIG Wires ER309L
Classification :
Product Details
ER309L is a low-carbon stainless steel TIG welding wire with stable chemical composition and excellent welding performance. It is specially used for GTAW / TIG welding of dissimilar metals, carbon steel to stainless steel, and general stainless steel structure connection.
With low carbon content, this wire effectively improves intergranular corrosion resistance and reduces carbide precipitation during welding. It features stable arc, smooth weld surface, easy operation, no splash, no porosity, and good fusion.
ER309L is widely used in food machinery, chemical equipment, pressure vessels, pipeline engineering, construction decoration, and metal fabrication. It provides reliable strength, toughness and corrosion resistance for long-term service.
