考登鋼管主要用于:高含硫煙氣中的省煤氣、空氣預(yù)熱器、熱交換器和蒸發(fā)器,用于抵御含硫煙氣的結(jié)露腐蝕。具有卓越的耐硫離子,耐鹽酸及其他酸性腐蝕的能力。nd鋼管是目前國內(nèi)外最理想的“耐硫酸低溫露點(diǎn)腐蝕”用鋼材,09CrCuSb(nd鋼管)鋼無縫鋼管/鋼板主要的考核指標(biāo)(70°50%H2SO4溶液中浸泡24小時(shí))腐蝕速率不大于14mg/cm·h,與碳鋼、日本進(jìn)口同類鋼、不銹鋼耐腐蝕能力相比教,是日本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。09CrCuSb(nd鋼管)鋼是以鍋爐;電爐的熱交換、煙管、煙囪等用途為目的開發(fā)的具有優(yōu)秀的耐硫酸露點(diǎn)腐蝕的熱軋鋼板、鋼管。其優(yōu)越的耐硫酸露點(diǎn)腐蝕的性能及非常高的性價(jià)比,是完全可以代替不銹鋼,超越不銹鋼(在耐硫酸露點(diǎn)腐蝕方面)的最好材料,nd鋼管具有重大經(jīng)濟(jì)意義,符合當(dāng)今高效.長壽.節(jié)能.環(huán)保等“綠色”觀念和國家發(fā)展政策導(dǎo)向。
Cauden steel pipe is 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 steel pipe is the most ideal "low temperature dew point corrosion resistant sulfuric acid" steel at home and abroad. The corrosion rate of 09CrCuSb (nd steel pipe) seamless steel pipe/steel plate is not more than 14mg/cm.h, which is 1.84 times higher than that of Japanese CR1R steel and 2.97 times higher than that of Cr18Ni9 steel. It is 8.63 times that of Corten steel and 14.11 times that of Q235B steel. 09CrCuSb (nd steel pipe) 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 and chimneys. 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 terms of sulfuric acid dew point corrosion resistance). The ND steel pipe has great economic significance and 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. 0CrMnTi是滲碳鋼,滲碳鋼通常為含碳量為0.17%-0.24%的低碳鋼。汽車上多用其制造傳動(dòng)齒輪,是中淬透性滲碳鋼中Cr Mn Ti 鋼,其淬透性較高,在保證淬透情況下,特別是具有較高的低溫沖擊韌性。20CrMnTi表面滲碳硬化處理用鋼。良好的加工性,加工變形微小,抗疲勞性能相當(dāng)好。主要用途有:用于軸類,活塞類零配件以及汽車,飛機(jī)各種特殊零件部位。
0CrMnTi is carburized steel. Carburized steel is usually low carbon steel with 0.17% - 0.24% carbon content. It is widely used in automobiles to manufacture transmission gears. It is a medium hardenability carburized steel with high hardenability, especially high low temperature impact toughness under the condition of guaranteed hardenability. 20CrMnTi steel for surface carburizing and hardening treatment. Good machinability, small deformation and good fatigue resistance. The main uses are: for axles, piston parts and special parts of automobiles and aircraft.
