Stainless Steel 446 is a high-chromium ferritic stainless steel that contains around 23–27% chromium and has very low carbon content. This unique composition gives it remarkable oxidation and corrosion resistance, particularly at elevated temperatures. The alloy boasts good strength, moderate ductility, and excellent scaling resistance even at high operating temperatures. Stainless Steel 446 pipes also feature low thermal expansion, good thermal conductivity, and strong resistance to sulphur-bearing environments, making them ideal for heat-intensive and corrosive industrial applications that demand a long service life.
