Understanding the corrosion resistance of different water qualities, the concentration of corrosive media, working conditions, flow rates, etc. is an effective way to correctly and reasonably select corrosion-resistant materials for water treatment. JN ALLOY has undertaken many water treatment projects. Some wastewater contains more granular media and high concentrations of Cl, therefore, high-N and high-strength 254SMO, Duplex steel 2205 and Super Duplex 2507 will be used relatively more.
