CORODUR® SP 206

Flux cored wires for Thermal Spray Application

EN ISO 14919 – 6 – 1,6 - 4

MATERIAL REVIEW

NiCrBSi cored wire to apply wear resistant and corrosion resistant protective coatings. Coatings can be sintered after application (self-fluxing). They reach hardness of 500 - 800 HV0,1 and show porosity of below 2%. The coatings can be machined by grinding and polishing. Designed for arc spraying but may also be sprayed by wire- and high-velocity-wire-flame-spraying.

APPLICATION

Used for high loaded components of chemical plants or food industry, plunger.
