work hardened |
Cobalt hardened nickel base alloy used for hardfacing of parts subjected to oxidation, corrosion and mechanical stresses at high temperatures. Typical applications : tube extrusion mandrels, hot shearing blades, extrusion tooling, forging dies. |

|
|
|
40 HRC |
Boron hardened nickel chrome alloys with increasing hardnesses, resistant to wear, friction and corrosion. The room temperature hardness is maintained to 650°C and drops gradually at higher temperatures. They possess a low coefficient of metal to metal friction permiting them to be used in valves and seals, high temperature conveyors, brick moulds and extrusion screws, etc. The deposit presents an excellent appearance, with a smooth bead and low dilution due to the low melting point of this alloy. |
