Sulfuric acid corrosion-resistant steel 09CrCuSbND steel

ND Steel is the best at home and abroad, "low temperature sulfuric acid dew point corrosion resistant" steel, ND steel is widely used in the economizer, air pre-heater, heat exchanger and evaporator made in the flue gas with high sulfur service etc. means equipment used to combat sulfur fumes dewpoint corrosion. ND Steel also has the ability to resist the chloride corrosion. ND steel main reference index (70 degrees Celsius 50% H2SO4 solution soak for 24 hours), and carbon steel, Japan's imports of similar steel, stainless steel, corrosion resistance compared to a higher than these steels. 09CrCuSb steel is a boiler; furnace heat exchange, the smoke pipe, chimney and other uses for the purpose of development has excellent corrosion resistance to sulfuric acid dew point of hot-rolled steel, steel pipe. Its superior performance and a very high price resistance to sulfuric acid dew point corrosion, is completely instead of stainless steel, stainless beyond (in terms of corrosion resistance to sulfuric acid dew point) of the best materials, ND steel has major economic significance, with the current efficiency. Longevity. Saving Environmentalists and other "green" ideas and national development policy orientation. 95 years won the national outstanding new products, the petrochemical company, the Department of Mechanical Science and Technology Award; eligible at the World Exposition held in the State Science Commission, 97 years into the GB150-1998 standards. August 1999 is eligible for technical assessment certificate issued by the National Commission on the pressure vessel, the State Bureau of Technical Supervision issued. Have been included in "processing high-sulfur crude oil is the main equipment design key equipment selection guidelines" SH / T3096-2001, "People's Republic of China / steel pressure vessel" GB150-1998 "within industry standards" Q / TDGG0039-2004 other countries and industries authoritative. The products are widely used in high-sulfur flue gas of coal-fired boiler, oil-fired boiler, economizer, air preheater, waste heat boilers, heat exchangers and other equipment and evaporator and a certain resistance to sulfuric acid dew point corrosion of various products , GB26132-2010 "sulfuric acid industry emission standards."
