09CrCuSb sulfuric acid corrosion resistant steel

09CrCuSb sulfuric acid corrosion resistant steel

09CrCuSb steel, also called ND steel, is the ideal steel for "sulphuric acid low temperature dew point corrosion resistance" at home and abroad. ND steel is widely used in the manufacture of economizers, air preheaters, heat exchangers and evaporators that serve in high-sulfur flue gas. equipment.
