Cornel C Co S
Alloy C type electrode for surfacing + cobalt
Description & applications
Special surfacing electrode with 170% recovery and a deposit composition of alloy C (Ni-Cr-Mo) Rutil-basic coating with outstanding welding characteristics. Deposit resists to corrosion in presence of hydrochloric acid (up to 160°C) and in general to all type of oxidation. Deposit work-hardanable under impact and machinable.
Cornel C Co S is destined in general to surface all pieces subject to mechanical stress combined with corrosion and/or to high temperatures (from 400 - 800°C) - Also used for pieces subject to high thermal shocks.
Principal applications: surfacing of hot working tools as hot shear blades, swages, dies, press tools as well as pump parts, installations for chlorination, valves and reservoirs.
