ND鋼（gāng）管簡要介紹： 09CrCuSb（ND鋼）鋼是以鍋爐；電爐的熱交（jiāo）換、煙管、煙囪等用途（tú）為目的開發的具有優秀的耐硫酸露點腐蝕的熱軋鋼（gāng）板、鋼（gāng）管。其優越的耐硫酸露點腐蝕的性能（néng）及非常高的性價比，是完全可（kě）以代（dài）替不鏽鋼，超（chāo）越不鏽鋼（在耐（nài）硫酸露點腐蝕方麵）的最好材料，ND鋼具有重大經濟意義，符合當今（jīn）高效.長壽.節能.環保等“綠色”觀念（niàn）和國家發展政策導向。
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：高含硫煙氣中的省煤氣、空氣預熱器、熱交換器和蒸發器，用（yòng）於抵禦含硫煙氣的結露腐蝕。具有卓越的耐硫離子，耐鹽酸及其他酸性（xìng）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鋼是目前國內外最理想的“耐硫酸低溫露點腐蝕”用鋼材，09CrCuSb（ND鋼）鋼無縫鋼（gāng）管/鋼板主要的考核指標（70°50%H2SO4溶液中浸泡24小時）腐蝕速率（lǜ）不（bú）大於14mg/cm·h，與碳鋼、日本進口同（tóng）類（lèi）鋼、不鏽鋼（gāng）耐腐蝕能力相比教，是日本CR1R鋼的1.84倍（bèi），是（shì）1Cr18Ni9鋼的2.97倍（bèi），是（shì）Corten鋼的8.63倍（bèi），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.
