If you’re looking for top-notch welding materials, check out AWS Class ER320LR MIG and TIG filler welding wire and rod. These high-quality stainless steel consumables are specifically crafted for welding duplex stainless steels. Whether you’re using MIG (Metal Inert Gas) or TIG (Tungsten Inert Gas) processes, ER320LR shines with its excellent weldability, creating robust, corrosion-resistant joints. This filler metal keeps the unique strength and toughness of duplex stainless steels intact, making it perfect for tough structural and industrial tasks where durability and resistance to stress corrosion cracking are a must.
Typically, AWS Class ER320LR has a composition of about 22-23% chromium, 3-4% molybdenum, 5-6% nickel, along with small amounts of nitrogen and manganese. This well-balanced chemical formula guarantees high corrosion resistance, particularly against chloride-induced stress corrosion cracking, while also maintaining impressive mechanical properties like high tensile and yield strength. The “LR” stands for low carbon content, which helps minimize carbide precipitation and boosts the toughness of the weld joint.
