JNS sulfuric-acid-dew-point-resistance steel has been put into practical use in the construction of steel-covered chimneys of the following electric power-generating stations: Zou xian Power Plant (2 1000 MW), Xiamen Songyu Power Plant (2 300 MW), Fujian Nanpu Power Plant(2 300MW),Shenzhen Power Plant (2 300MW). Many experienced experts held discussions with designers at scene and reached a unanimous conclusion that "JNS sulfuric-acid-dew-point-corrosion -resistance steel " is more stable in terms of function, more convenient to weld and process and more safe to use than " past sulfuric-acid-dew-point-resistance steel". Reports from various laboratories demonstrate that "JNS sulfuric-acid-dew-point-corrosion -resistance steel " is more effective to resist acid corrosion than the former steel , and many exports predict after thorough study that this acid of steel have a life span longer than 30 years being used in de-sulfurized chimneys and it is much less expensive than titanium alloy clad plates and Peenguard, etc.
