Main is ferrite microstructure, not α = γ transformation during heating and cooling, heat treatment cannot be used to strengthen. Strong antioxidant. At the same time, it also has good thermal processing and some cold machinability. Ferritic stainless steel is used for making requires high corrosion resistance and low strength requirements artifacts, widely used in the manufacture of production equipment and chemicals such as nitric acid, nitrogen fertilizer use of pipelines.
