CORODUR® SP 103
Flux cored wires for Thermal Spray Application
EN ISO 14919 – 5 – 1,6 - 4
MATERIAL REVIEW
Flux cored wire composition based on iron used for abrasion and corrosion resistant coatings showing high bond strength. Coatings can be polished, and they are ductile and thermal resistant up to 870°C. Designed for arc spraying but may also be sprayed by wire- and high-velocity-wireflame-spraying.
APPLICATION
Used as erosion protection coating on water walls of boilers, cyclons, within steam turbines.
