AWS Class ER308/308H SAW wires and flux are widely used for welding austenitic stainless steels, especially 18Cr-8Ni grades. They are ideal for applications requiring corrosion resistance, high strength, and durability. Common uses include chemical and petrochemical equipment, pressure vessels, food processing machinery, heat exchangers, and structural components exposed to high temperatures or harsh environments. ER308H is preferred for elevated-temperature service due to its higher carbon content. These consumables ensure smooth, defect-free welds with deep penetration and excellent mechanical properties, making them a trusted choice for industrial fabrication, shipbuilding, power plants, and stainless steel construction projects.
