ND钢管简要介绍： 09CrCuSb（ND钢）钢是以锅炉；电炉的热交换、烟管、烟囱等用途为目的开发的具有优秀的耐硫酸露点腐蚀的热轧钢板、钢管。其优越的耐硫酸露点腐蚀的性能及非常高的性价比，是完全可以代替不锈钢，超越不锈钢（在耐硫酸露点腐蚀方面）的最好材料，ND钢具有重大经济意义，符合当今高效.长寿.节能.环保等“绿色”观念和国家发展政策导向。
ND Steel Pipe Brief Introduction: 09CrCuSb (ND Steel) steel is a hot rolled steel plate and steel pipe with excellent sulfuric acid dew point corrosion resistance developed for the purpose of heat exchange of boilers, electric furnaces, flue pipes, chimneys and other purposes. Its superior sulfuric acid dew point corrosion resistance and very high cost performance are the best materials that can completely replace stainless steel and surpass stainless steel (in sulfuric acid dew point corrosion resistance). ND steel is of great economic significance, which is in line with the current "green" concept of high efficiency, long life, energy saving and environmental protection and the guidance of National Development policy. 主要用于：高含硫烟气中的省煤气、空气预热器、热交换器和蒸发器，用于抵御含硫烟气的结露腐蚀。具有卓越的耐硫离子，耐盐酸及其他酸性腐蚀的能力。
Mainly used for saving gas, air preheater, heat exchanger and evaporator in high sulfur flue gas, to resist condensation corrosion of sulfur flue gas. Excellent sulfur ion resistance, hydrochloric acid resistance and other acid corrosion resistance.
ND钢是目前国内外最理想的“耐硫酸低温露点腐蚀”用钢材，09CrCuSb（ND钢）钢无缝钢管/钢板主要的考核指标（70°50%H2SO4溶液中浸泡24小时）腐蚀速率不大于14mg/cm·h，与碳钢、日本进口同类钢、不锈钢耐腐蚀能力相比教，是日本CR1R钢的1.84倍，是1Cr18Ni9钢的2.97倍，是Corten钢的8.63倍，是Q235B钢的14.11倍。
ND steel is the most ideal steel for "low temperature dew point corrosion resistance to sulfuric acid" at home and abroad. The corrosion rate of 09CrCuSb (ND steel) seamless steel pipe/steel plate is less than 14mg/cm.h, which is 1.84 times higher than that of Japanese CR1R steel, 2.97 times higher than that of Cr18Ni9 steel and 2.97 times higher than that of carbon steel, Japanese imported similar steel and stainless steel. The orten steel is 8.63 times as much as Q235B steel and 14.11 times as much as Q235B steel.
