Model Number: Gas cylinder steel,Weathering steel
Key Specifications/Special Features:
Pressure vessel steel:Mainly used for pressure vessel manufacturing as welding gas cylinders, liquefied petroleum gas cylinders, acetylene cylinders and oxygen cylindersWeathering steel:Good mechanical, welding property and weather resistance (high weather resistance), low crack sensitivity, fine machine shaping, precise dimension, good slab shape and surface qualityMainly used in manufacturing rail truck, stadiums and chemicalAcid-resistant steel:High weather resistance and sulfur corrosion resistance
Mainly used in some place where sulfur corrosion resistance is necessary, such as coal-fired switch, power chimney, tobacco flue-curing house
For the application in tobacco industry, our product has passed acid resistance testing of the products Huazhong University of science and technology
We has acquired production license of China National Tobacco Corporation
