Type 441 (UNS S44100) is a ferritic rolled coil stainless steel with a niobium (columbium) addition that has good oxidation and corrosion resistance, as well as good high-temperature strength. 441 is similar to AK Steel 18 Cr-Cb™.
441 rolled coil stainless steel is used mainly for high-temperature settings and corrosive environments, particularly automotive-exhaust system components.
