09CrCuSb seamless pipe successfully delivered (2020-12-24)

On December 1, 2020, our company successfully delivered ND steel (09CrCuSb) seamless steel pipes.

09CrCuSb ND steel is a new type of steel resistant to sulfuric acid low temperature dew point corrosion developed by Shanghai Institute of materials and Xingcheng Special Steel from 1987 to 1990

ND steel is a low alloy structural steel. Compared with other steels such as low carbon steel, corten and cr1a, ND steel has excellent corrosion resistance and mechanical properties.

Details

09CrCuSb (ND steel) steel is developed for coal-fired boilers, oil-fired boilers; heat exchangers for electric furnaces, pipes, chimneys, boiler air preheaters, economizers, heat exchangers, condensing coolers, evaporators, etc. Hot-rolled steel sheets and steel pipes with excellent resistance to sulfuric acid dew corrosion. Its superior resistance to sulfuric acid dew point corrosion and very high cost performance is the best material that can completely replace stainless steel and surpass stainless steel (in terms of sulfuric acid dew point corrosion resistance). ND steel has great economic significance, in line with today's high efficiency, longevity and energy saving. "Green" concepts such as environmental protection and national development policy orientation.

Advantage of 09CrCuSb (ND steel)

ND steel, 09CrCuSb steel, is the most ideal steel for “sulfuric acid resistant low temperature dew point corrosion” at home and abroad. ND steel is widely used in the manufacture of economizers, air preheaters, heat exchangers and in high sulfur flue gas. Equipment such as evaporators, used to resist corrosion of sulfur-containing flue gas dew point. ND steel also has the ability to resist chloride ion corrosion. The main reference index of ND steel pipe (soaked in 50% H2SO4 solution at 70 °C for 24 hours) is higher than that of carbon steel and stainless steel.
