StarBlaze TIG Wire ER347

STARBLAZE TIG 347 is a premium, niobium-stabilised austenitic stainless steel TIG welding rod engineered for precision Gas Tungsten Arc Welding (GTAW).
It complies strictly with international standards like AWS A5.9 ER347. Because it is fortified with niobium (columbium), it effectively restricts chromium carbide precipitation during thermal cycling.
This core feature eliminates sensitization and guarantees exceptional resistance to intergranular corrosion.

Product Overview & Composition
Alloy Classification: Conforms to the standard AWS A5.9: ER347 and EN ISO 14343-A: W 19 9 Nb.
Chemical Profile: Formulated with a balanced blend of 19% Chromium (Cr) and 9% Nickel (Ni).
Niobium Stabilization: Specially enriched with niobium (Nb) to prevent weld-decay and intergranular breakdown under long-term exposure to critical heat zones.
Corrosion Resistance: Retains high chemical and mechanical integrity against aggressive corrosive media at continuous service temperatures below 400°C.
