Resistance of high-silicon ferroalloy to nitric acid corrosion

High-silicon ferroalloy resists nitric acid and fuming nitric acid at all concentrations and up to the boiling point; as the temperature increases, its corrosion resistance changes only slightly. For acids with a concentration of over 45%, when the temperature reaches the boiling point, their corrosion rate is practically zero. Weak acids cause slight corrosion on it, as stainless steel is not heat-resistant; concentrated nitric acid also poses a problem. Therefore, in harsh conditions of high temperature, high concentration, and corrosive wear, equipment made of high-silicon iron, such as pumps, valves, pipes and fittings, condensers, etc., is widely used. Additionally, its price is much lower than that of stainless steel and other materials resistant to nitric acid, which is also one of its advantages.
