Product Description
Hardfacing Stellite 21 Cobalt Based welding Bare Rods Stellite 21 Aws ERCoCr-E(Co121))
Product description
Cobalt base alloys are available as cobalt rods, cobalt electrodes, cobalt wire and cobalt powder. Cobalt alloys are used primarily for wear applications, our cobalt alloys can be applied by any known fusion welding process or HVOF spraying proess and are particularly well-suited for hardfacing applications. Cobalt alloys are the most widely used wear resistant hardfacing materials available. Their unique combination of wear resistance, strength and corrosion resistance make them adaptable to many harsh environments.
