Description
The ER347H 2.4mm TIG Wire 5kg is a niobium-stabilized stainless steel TIG filler rod designed for welding high-carbon versions of 347 stainless steel. The “H” designation indicates higher carbon content, which improves creep resistance at elevated temperatures. This makes the wire ideal for high-temperature, high-pressure service in boilers, heat exchangers, and petrochemical plants.
Containing niobium and elevated carbon, ER347H TIG wire helps maintain structural integrity under prolonged heat exposure. It performs especially well in continuous service environments above 600°C, where standard 347 or 308 wires might fail. The niobium content prevents carbide precipitation, reducing the risk of intergranular corrosion.
At 2.4mm diameter, the wire offers excellent arc control and smooth bead formation. Welders can achieve clean, strong welds with minimal spatter. It’s suitable for piping, pressure vessels, and stainless components that operate under thermal stress.
Use this wire with DC+ polarity on stainless steel base metals, especially those with higher carbon levels. The 5kg spool provides enough material for fabrication work while staying manageable for smaller teams or on-site welding tasks. This wire excels in industries such as chemical processing, energy, and high-temperature structural fabrication.
When welding stabilized stainless steels like 347H, it’s important to use filler material that matches the base metal’s performance. ER347H ensures compatibility and maintains corrosion resistance in the heat-affected zone—helping you meet welding codes and project specifications.
