Stainless Steel 446 is a high-chromium ferritic stainless steel that contains 23–27% chromium and has a very low carbon content. This unique composition gives it outstanding resistance to oxidation, scaling, and corrosion at elevated temperatures. SS 446 Stud Bolts showcase high tensile and yield strength, good thermal stability, and excellent resistance to sulfur-rich and high-temperature environments. Although they have lower ductility compared to austenitic grades, their strength and structural integrity remain stable even under continuous high-heat exposure, making them perfect for demanding industrial applications.
