What Are Thermanit H-347 TIG Rods?
Thermanit H-347 TIG Rods are solid, high-alloyed stainless-steel filler rods used in TIG welding. The stabilized austenitic filler metal is classified as ER347 under AWS A5.9 / SFA-5.9 and W 19 9 Nb under EN ISO 14343-A.
The alloy contains chromium and nickel, with niobium stabilization. Product literature describes resistance to intercrystalline corrosion and wet corrosion up to 400°C. Its corrosion resistance is comparable to matching stabilized austenitic chromium-nickel stainless steels and suitable cast-steel grades.
Filler-metal selection must be based on the parent material, service environment, operating temperature, design requirements and approved welding procedure. Always confirm compatibility using the current manufacturer's technical datasheet.
