Stellite 12 Welding Wire | UNS R30012 Cobalt Alloy Wire

Description Of Stellite 12 Welding Wire

Stellite 12 Welding Wire is a high-performance hardfacing wire manufactured from Stellite 12 (UNS R30012), a cobalt-chromium-tungsten alloy known for its exceptional wear resistance, high-temperature strength, and corrosion resistance. Stellite 12 contains approximately 30% chromium, 8.5% tungsten, and 1.4% carbon, providing a balance of hardness and toughness ideal for hardfacing applications.

Stellite 12 welding wires are widely used for hardfacing valve seats, pump sleeves, cutting tools, and other components subject to severe wear. The alloy maintains its hardness and mechanical properties at elevated temperatures up to 800°C, making it suitable for high-temperature and high-wear applications. The wire is suitable for TIG welding and oxy-acetylene welding, providing a smooth, crack-free deposit.

Stellite 12 welding wires are available in custom diameters and spool sizes, with surface finishes including bright, pickled, and polished. Typical applications include hardfacing valve seats, pump sleeves, cutting tools, and wear-resistant components.
