UNS R30006

ECoCr-B Stellite 6 Electrode/Rod

The most widely used cobalt hardfacing deposit, balancing wear and impact.

Material overview

The Cobalt Alloy Welding Consumables catalog describes ECoCr-B Stellite 6 Electrode/Rod as follows: The most widely used cobalt hardfacing deposit, balancing wear and impact. Reviewers should evaluate HRC 39-45, all-purpose wear/corrosion, and moderate impact. The grade record lists Valve seats, pump shafts, screw conveyors, engine valves, and dies among typical applications. The dataset currently includes 7 property records covering chemical composition and mechanical properties. Standards and form records reference A5.21 and A5.13 and Bar / Rod, Covered Electrode, and Solid Wire / GTAW-GMAW Wire. Final supply conditions remain subject to specification, inspection, and export-control review.
