Stainless Steel ER347Si Filler Wire comprises a combination of chromium and nickel elements. Chromium provides corrosion resistance and increases strength, while nickel contributes to the material's ductility and high-temperature properties. Trace amounts of other factors, such as molybdenum, Nitrogen and silicon also add to the overall composition; molybdenum provides additional strength, Nitrogen improves weldability, and silicon increases the welding speed. This stainless steel offers superior hardenability compared to many Stainless Steel types, making it an excellent option for a denser product with additional durability.

SS ER347Si Filler Wire is a valuable metal alloy used in industrial welding operations. Its chief uses include joining, surfacing, and repairing stainless steel components. It provides corrosion resistance to form a tight bond between the two pieces of metal, making it perfect for dissimilar welding metals. The weld joints created by this wire feature outstanding crack-resistance properties and robust mechanical properties such as tensile strength, heat resistance and impact toughness. Moreover, it also offers excellent fatigue endurance, making it perfect for applications requiring extended operational life cycles. By using this wire and matching base metals, excellent weld bead aesthetics can also be achieved for aesthetic purposes.

FAQ's for Stainless Steel ER347Si Filler Wire

Stainless steel ER347Si filler wire is a corrosion-resistant austenitic stainless steel alloy composed of 25% chromium, 4% nickel, 5% silicon and 0.04% carbon.
