ND steel is selected for boiler air heater, gas saver, heat exchanger, condenser cooler and evaporator
09CrCuSB (ND steel company code) is a steel used for corrosion resistance at low sulfuric acid dew point temperature (ND steel plate, ND steel pipe, 09CrCuSB steel plate, 09CrCuSB steel pipe, etc.)

In 1995, it was rated as National Excellent New Product, awarded the Second Prize of Science and Technology by Sinopec and the Ministry of Machinery Industry; won the Gold Award in the World Expo held by the National Science and Technology Commission, and was listed in GB150-1998 standard in 1997. In August 1999, it was awarded the technical assessment certificate by the National Pressure Vessel Committee and the National Bureau of Technical Supervision. authoritative standards egypt number data such as SH/T3096-2001, People's Republic of China/Steel Pressure Vessels GB150-1998, Domestic Industrial Standards Q/TDGG0039-2004 and so on, which are the basic guidelines for equipment design and material selection for sour crude oil processing. It is widely used in high-sulfur flue gas, coal-fired boiler, fuel boiler, economizer, air heater, heat exchanger, evaporator and other equipment, and various products with a certain corrosion resistance at sulfuric acid dew point.

ND steel is currently the most ideal steel for "low sulfuric acid dew point corrosion resistance" both at home and abroad. The main evaluation index for 09CrCuSb (ND steel) seamless steel pipe/plate (soaking in 7050% H2SO4 solution for 24 hours) is that the corrosion rate is not more than 14mg/cm. h. Compared with carbon steel similar to that imported from Japan and stainless steel, its corrosion resistance is 1.84 times that of Japanese CR1R steel, 2.97 times that of 1Cr18Ni9 steel, 8.63 times that of Corten steel, and 14.11 times that of Q235 steel.
