Kyaw Stainless, a prime stainless steel consumable producer in Naypyidaw, Myanmar, provides premium quality AWS Class ER347 MIG and TIG Filler Welding Wires and Rods. Engineered to weld stabilized stainless steels, these fillers offer superior resistance to carbide precipitation and intergranular corrosion. Kyaw Stainless has rigorous quality standards to ensure maximal weldability, mechanical properties, as well as corrosion resistance. ER347 rods and wires are best suited for welding niobium- or titanium-stabilized stainless steels like 321 and 347 grades and are used in large scale in petrochemical, power plants, and food processing industries.
ER347 filler wires have chromium (18–20%), nickel (9–11%), niobium/columbium (8–10×C minimum), and low carbon (<0.08%). The weld metal has tensile strength of approximately 600 MPa, yield strength approximately 400 MPa, and elongation approximately 35%. The addition of niobium stabilizes the structure, inhibiting carbide precipitation and sustaining corrosion resistance after high-temperature exposure. The filler has fine mechanical stability, toughness, and protection against oxidation and intergranular attack in austenitic stainless steel welds.
