Features and Applications
Cobalt base tubular wire for gas-shielded metal arc hardfacing.
Exceptional resistance in corrosive media at high temperatures, including erosion and thermal shocks.
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, impact and corrosive environments.
Precision layer wound for superior wire feeding characteristics.
Extensively used on valve seats of diesel engines, cams, chainsaw bars, hot shear blades, cold forming rolls and hot forming rolls, for hot rolling reinforcing bar, pump parts and components in hot zinc baths etc.
