AWS A5.9: ER 430 | EN ISO 14343-A: G 17
StarBlaze TIG 430 is a 16% chromium stainless steel TIG wire designed for welding ferritic stainless steels. The alloy composition is optimised to ensure good corrosion resistance for typical applications while maintaining sufficient ductility in the heat-treated condition. Preheating and post-weld heat treatment are generally recommended to achieve optimal mechanical properties and corrosion resistance. It is ideal for use in the fabrication and repair of components such as exhaust systems, automotive parts, and architectural applications.
