CORODUR® SP 105 HY

Flux cored wires for Thermal Spray Application

EN ISO 14919 – 5 – 1,6 - 4

MATERIAL REVIEW

Special alloy with a high content of Chromium and Cobalt. The coating shows austenitic structure with increasing hardness in service. Coatings are very resistant against corrosion, erosion and in particular against cavitation. Designed for arc spraying but may also be sprayed by wireand high-velocity-wire-flame-spraying.

APPLICATION

Typical applications can be found as protection coatings against cavitation and erosion in the field of water turbines, hydraulics and gas system components.
