Photos of ND steel (09CrCuSb) seamless steel tubes

ND steel, namely 09CrCuSb steel, is currently the most ideal steel for "resistance to low-temperature sulfuric acid dew point corrosion" (ND steel plate, ND steel tubes, 09CrCuSb steel plate, 09CrCuSb steel tubes, etc.)

ND (09CrCuSb) steel 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.

Comparison of corrosion rate between ND steel and other steel grades (70 ℃-50% H2SO4 solution)
