AWS A5.9: ER 347H | EN ISO 14343-A: W 19 9 Nb
StarBlaze TIG 347H is a niobium-stabilised stainless steel TIG welding rod that deposits a 19Cr/9Ni weld metal, designed for use with Argon shielding gas. It is ideal for welding 321 and 347 grade stainless steels in applications such as pipe, plate, and pressure vessel fabrication. The addition of niobium provides excellent resistance to intergranular corrosion, particularly at service temperatures below 400°C.
