Ferritic stainless steel generally has a Cr content between 13%-30%, and a C content generally less than 0.25%. After annealing or aging, carbides precipitate at the ferrite grain boundaries to achieve corrosion resistance.
Generally speaking, the corrosion resistance of ferritic stainless steel is lower than that of austenitic stainless steel and duplex steel, but higher than that of martensitic stainless steel. However, due to its low production cost compared to other stainless steels, it has a wide range of applications in the fields of chemical and petrochemical applications where corrosion-resistant media and strength are not required.
For example, it is widely used in environments such as sulfur-containing petroleum, hydrogen sulfide, room temperature nitric acid, carbonic acid, hydrogen ammonia mother liquor, high-temperature ammonia produced by urea, urea mother liquor, and vinyl acetate and acrylonitrile produced by Vinylon.
