CORODUR® SP 233

Flux cored wires for Thermal Spray Application

EN ISO 14919 – 6,5 – 1,6 - 4

MATERIAL REVIEW

Very high bond strength, also on smooth surfaces, self-bonding due to exothermic reaction, very dense coatings. Can be applied on clean but not sand blasted surfaces. Best bonding if applied in one pass (about 0,125 mm). Coating is easy to machine. Designed for arc spraying but may also be sprayed by wire- and high-velocity-wire-flame-spraying.

APPLICATION

Bond coat with good oxidation and high temperature resistance up to 650°C.
