Features and Applications
Cobalt base tubular wire for gas-shielded metal arc hardfacing.
Exceptional resistance in corrosive media at high temperatures.
Ideal for hardfacing parts undergoing the single or combined effects of heavy metal-to-metal wear or abrasion, temperatures ranging from RT to 800°C and corrosive environments.
Precision layer wound for superior wire feeding characteristics.
Typically used on steam valves, wire guides, rubber and plastic mixers, extrusion screws, conveyors etc.
