Description Of Stellite 12 Round Bar
Stellite 12 Round Bar and Rod are high-performance products 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 and wear-resistant applications.
Stellite 12 round bars are widely used as starting stock for machining valve seats, pump sleeves, and cutting tools. Stellite 12 rods are commonly used as TIG welding filler rods for hardfacing these components. 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.
Stellite 12 round bars and rods are available in custom diameters and lengths, with surface finishes including machined, ground, and polished. Typical applications include valve components, pump sleeves, cutting tools, and wear-resistant parts.
