Products Description
09CrCuSb (ND) High-Performance Corrosion-Resistant Seamless Tubes are widely used in the manufacture of economizers, air preheaters, heat exchangers and evaporators that are used in 100-high sulfur-containing flue gas, to resist dew point corrosion of sulfur-containing flue gas.
ND (09CrCuSb) steel tube also has the ability to resist chloride ion corrosion. The main reference standard of ND steel pipe is internal standard (soaked in 50% H2SO4 solution at 70 degrees Celsius for 24 hours).
Compared with other steels such as low carbon steel, corten and cr1a, ND steel has excellent corrosion resistance and mechanical properties.
