Kanthal SW 200 is an austenitic nickel-chromium alloy (NiCr alloy) for use in arc and flame spray systems. The alloy produces dense, well bonding coatings resistant to high-temperature oxidation and corrosion.

Typical applications for Kanthal SW 200 are protective coatings against corrosive gases, protection against scaling of conventional low alloy steels and build-up coatings for dimensional restoration.

Machining

Depending of surface finish requirements, the coating may be machined by turning or grinding. For rougher surface, turning using carbide tools, light cuts and efficient cooling to avoid overheating is recommended. Grinding in fine steps using cooling, light pressure and clean wheels gives smoother finish.
