Sandvik Kanthal SW 921 Spray wire
Categories: Metal; Ferrous Metal; Superalloy; Nickel Base

Material Notes: Kanthal SW 921 is an austenitic chromium-nickel-molybdenum-copper alloy (CrNiMoCu alloy) for use in arc and flame spray systems. The alloy produces dense, well bonding coatings resistant organic and nonoxidizing organic acids at high temperatures. The excellent corrosion and oxidation resistance of Kanthal SW 921 combined with its high strength makes the alloy suitable for boiler applications, restoration, paper machinery and textile machinery.
