The AWS Class E347T1-1/T1-4 flux core wires are formulated with about 18–20% Chromium, 9–13% Nickel, and 0.8–1.2% Niobium (Columbium), all while keeping the carbon content low (≤0.08%) to avoid carbide precipitation and intergranular corrosion. These wires boast impressive mechanical properties, including a tensile strength of at least 550 MPa, yield strength of at least 380 MPa, and an elongation of at least 30%. They can be used with both 100% CO₂ shielding gas (T1-1) and mixed shielding gases (T1-4), providing versatility for different welding scenarios. The rutile flux coating ensures smooth arc behavior, easy slag removal, and a great bead appearance, especially in flat and horizontal welding positions.
Premium dual shield flux cored wire providing excellent corrosion resistance and weld stability. Ideal for applications requiring external shielding gas, such as in petrochemical, shipbuilding, and construction projects where high-quality welds are crucial.
High-performance self-shielded flux cored wire for outdoor and field welding without external shielding gas. Delivers superior corrosion resistance and mechanical strength, suitable for construction, repair work, and fabrication in challenging environments.
Versatile flux cored arc welding wire offering excellent weld quality, corrosion resistance, and mechanical properties. Perfect for various industrial applications including pressure vessels, pipelines, and structural components exposed to demanding conditions.
These flux core wires are perfect for welding 347 and 347H stainless steel base metals in environments that experience cyclic heat and corrosive conditions, such as boilers, heat exchangers, pressure vessels, and chemical processing equipment. Their outstanding resistance to thermal sensitization makes them ideal for critical welds that need to withstand high-temperature service. MERIH STAINLESS distributes these wires worldwide, offering welders dependable consumables that comply with international standards for performance and quality.
The AWS Class E347T1-1/T1-4 Flux Core Wire is widely utilized in industries that require robust, corrosion-resistant welds, such as chemical processing, petrochemical, and power generation.
