Q345NS acid resistant steel plate
Q345NS acid-resistant steel is a high-quality corrosion-resistant steel containing chromium, nickel, molybdenum and other elements to form a dense oxide film to resist acid corrosion. It has excellent mechanical and welding properties, advanced manufacturing technology and stable quality. It is widely used in chemical, petroleum, pharmaceutical and other fields to extend equipment life and reduce maintenance costs.
Q315NS acid resistant steel plate
Q315NS acid-resistant steel plate is a specially designed material, which is famous for its excellent acid resistance and is widely used in equipment and piping systems in chemical, petroleum, pharmaceutical, food and other industries.
09CrCuSb acid resistant steel plate
09CrCuSb (ie 09CRCUSB) acid-resistant steel plate is a special steel with excellent corrosion resistance and mechanical properties. It is a low-alloy, high-strength acid-resistant steel plate, mainly used in equipment manufacturing and building structures in the fields of chemical, petroleum, fertilizer, and pharmaceuticals.
The acid resistance of acid-resistant steel is mainly determined by the chemical composition of the steel (the content of elements such as Ni, Cr, Mo, Cu, and Si). Generally, acid-resistant steel has good corrosion resistance in oxidizing acids (nitric acid and sulfuric acid), but is not corrosion-resistant or not corrosion-resistant enough in reducing acids (hydrochloric acid, etc.). For example, it is not corrosion-resistant in hydrochloric acid except for very dilute solutions and at room temperature. There are brands such as 09CrCuSb, Q315NS, and Q345NS.
