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是渗碳钢，渗碳钢通常为含碳量为0.17%-0.24%的低碳钢。汽车上多用其制造传动齿轮，是中淬透性渗碳钢中Cr Mn Ti 钢，其淬透性较高，在保证淬透情况下，特别是具有较高的低温冲击韧性。20CrMnTi表面渗碳硬化处理用钢。良好的加工性，加工变形微小，抗疲劳性能相当好。主要用途有:用于轴类，活塞类零配件以及汽车，飞机各种特殊零件部位。
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.
