CORODUR® SP 231
Flux cored wires for Thermal Spray Application
EN ISO 14919 – 5 – 1,6 - 4
MATERIAL REVIEW
Excellent bond strength due to exothermic reaction used as bond coats for repair of machinable C-steels and corrosion resistant steels. Good resistance against particle erosion and increased wear resistance due to Mo content. Designed for arc spraying but may also be sprayed by wire- and high-velocity-wire-flame-spraying.
APPLICATION
Application for bearing areas, and repair of parts out of tolerance or worn out components.
