ND鋼（gāng）管簡要介紹： 09CrCuSb（ND鋼）鋼是以鍋爐（lú）；電（diàn）爐的熱交換、煙管、煙囪等用途為目的開發的具有優秀的（de）耐硫酸露（lù）點腐（fǔ）蝕的熱軋鋼板、鋼管。其優越的耐硫（liú）酸露點腐蝕的性能及非常高的性價比，是完全可以代替不鏽鋼，超越不鏽鋼（在耐硫酸露點腐蝕方麵）的最好材（cái）料，ND鋼具有重大經濟意義，符合（hé）當今高效.長壽.節能.環保等（děng）“綠色”觀念和（hé）國（guó）家發展政策導向。
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. 主要用於：高含硫煙氣中的省（shěng）煤氣、空氣預熱器、熱交換器和（hé）蒸（zhēng）發器，用於抵禦含硫煙氣的結露腐蝕。具有卓越的（de）耐硫離子，耐鹽（yán）酸及其他酸性腐（fǔ）蝕的能力。
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鋼（gāng）是目前國內外最理（lǐ）想的“耐硫酸低溫露點腐蝕”用鋼（gāng）材，09CrCuSb（ND鋼）鋼無（wú）縫鋼管/鋼板主要的考核指標（70°50%H2SO4溶液中浸泡24小（xiǎo）時）腐蝕速率不大於14mg/cm·h，與碳鋼、日本進口（kǒu）同（tóng）類鋼、不（bú）鏽鋼耐腐蝕能力相比教，是（shì）日本CR1R鋼的1.84倍，是1Cr18Ni9鋼的2.97倍，是Corten鋼的8.63倍，是Q235B鋼的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.
