CORODUR® SP 227

Flux cored wires for Thermal Spray Application

EN ISO 14919 – 6 – 1,6 - 4

MATERIAL REVIEW

NiCrMoW alloy, like CORODUR SP 226, applied as very corrosion resistant coating, e.g. protective against chloride acids, and also resistant against oxidation and hot gas corrosion. Coating shows higher hardness than CORODUR SP 226. Designed for arc spraying but may also be sprayed by wire- and high-velocity-wire-flame-spraying.

APPLICATION

Typical applications are as bond coat and for repair in chemical industry, petro chemical industry and for off-shore applications.
