09CrCuSb Alloy Steel Seamless Tube Corrosion Resistance For Preheater And Heat Exchanger

09CrCuSb tube is a kind of alloy steel tube widely used in preheater and heat exchanger. It is widely used in power plants and refineries to manufacture coal economizers, air preheaters, heat exchangers and evaporators which work in high sulfur flue gas to resist condensation corrosion of sulfur flue gas.

The low-alloy ND steel 09CrCuSb, which is resistant to sulfuric acid dew point corrosion for seamless steel tubes, plates, forgings and special welding materials, was prepared by smelting in ultra-high power electric furnace, refining outside furnace and vacuum degassing. It is characterized by the formation of a dense passivation film rich in Cr, Cu, Sb and Ti on its surface during the corrosion process, so it has a high anticorrosion ability.

ND steel is a low alloy structural steel.Compared with other types of steel such as mild steel, Corten, CR1A, ND steel has excellent corrosion resistance and mechanical properties.
