Kanthal^® SW 230 is an austenitic iron-nickel-chromium alloy (FeNiCr alloy) for use in arc and flame spray systems. The alloy produces dense, well bonding coatings resistant to high-temperature oxidation.

Typical applications for Kanthal^® SW 230 are protective coatings against corrosive gases, protection against scaling of conventional low alloy steels and build-up coatings for dimensional restoration.
