441Ferritic Grade
Grade Overview
Introduction & Overview — SS 441 Coils / AISI 441 Coils (1.4509 / 441HT)
SS 441 Coils (EN 1.4509) are niobium and titanium stabilized steel coils specifically developed for high-temperature use. They provide superior performance when compared with traditional ferritic grades like SS 409 and are suitable for exhaust and heat-exposed applications. Their stable ferritic microstructure and chromium content prevent scaling and oxidation, while dual stabilization reduces intergranular corrosion during welding and extended heat exposure.
