    This document provides information on a solid TIG wire for welding HP40Nb alloys, including its composition, mechanical properties, typical operating parameters, packaging, and fume data. The wire has a composition designed to match HP40Nb alloys with a minimum niobium content of 0.75% and maximum of 1.5%. Typical mechanical properties show tensile strength over 800 MPa and elongation over 9% for TIG welds. The wire is spooled and packaged in tubes weighing 2.5kg and is used with argon shielding gas at 100A and 12V for TIG welding. Fume analysis shows iron, manganese, and chromium make up over 75% of the fume composition with

    * Parent material minimum values (static castings).
    Room temperature elongation has little significance for weld metal designed for high temperature service and creep
    resistance. Values down to 4.5% (on 4d) are allowed in ASTM HP40 castings and the ductility of multipass welds
    may approach this value due to carbide precipitation in successive runs.
