Stainless Steel Solid TIG Wires ER347
Classification :
Product Details
ER347 is a stabilized stainless steel TIG welding rod designed for high-performance welding of 321 / 347 grade stainless steels. It contains niobium (Nb) stabilization to prevent intergranular corrosion and improve heat resistance.
This wire delivers stable arc, clean weld pool, smooth bead formation, and excellent mechanical properties under high-temperature service conditions. It offers strong resistance to carbide precipitation, cracking, and corrosion, making it ideal for critical applications.
Suitable for TIG welding of heat-resistant stainless steel components in boilers, pipelines, pressure vessels, exhaust systems, and high-temperature equipment. Widely used in petrochemical, power generation, aerospace, and industrial fabrication.
