StarBlaze TIG 321
AWS A5.9: ER 321 | EN 12072: W 19 9 Ti
StarBlaze TIG 321 is a titanium-stabilised 19Cr/9Ni austenitic stainless steel TIG wire, designed for welding stainless steels such as AISI 304, 304L, 308, 308L, 321, and 347. The addition of titanium binds with carbon to prevent intergranular chromium carbide precipitation, enhancing corrosion resistance and mechanical stability. This wire is ideal for applications requiring long-term resistance to high-temperature environments, commonly used in the petrochemical, food processing, and energy industries.
