CORODUR® SP 225
Flux cored wires for Thermal Spray Application
EN ISO 14919 – 6 – 1,6 - 4
MATERIAL REVIEW
NiCrMo alloy, comparable to 2.4831 to produce very corrosion resistant coatings, e.g. protective against chloride acids, and also resistant against oxidation and hot gas corrosion. Used as bond coat and for repair. 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.
