Cobalt Alloy Rod

Cobalt Alloy Rods (or round bars) are semi-finished products used for welding, hard-facing, or machining components subject to severe high-temperature wear and corrosion. Zeron Fastners supplies rods utilizing alloys such as Stellite and Haynes 25. These rods maintain superior hardness and mechanical strength even when red hot, due to the high content of chromium, tungsten, and molybdenum carbides. They are vital for extending the service life of high-wear components. The primary application of these Cobalt Alloy Rods includes fabrication of jet engine parts, turbine blades, valve stems, and wear-resistant bushings.
