CORODUR® SP 228
Flux cored wires for Thermal Spray Application
EN ISO 14919 – 6 – 1,6 - 4
MATERIAL REVIEW
NiCrBSi flux cored wire alloy with about 10 – 15% primary carbides. High wear resistance against abrasion and corrosion, e.g. for components loaded by chemical fluids containing abrasive particles. Can be sintered (self-fluxing). 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 as plunger and shafts.
