Seamless steel pipe is more and more people are familiar with, but few people know what it is mainly is widely used in place, here are some introduction: special steel for the bridge as "16Mnq", special steel automobile frames species "16MnL", special steel pressure vessel is "16MnR". Such adjustment is to rely on the carbon steel (C) amount to improve the mechanical properties of the steel, and therefore steel manufacturers, according to the level of the carbon content, these steels can be divided into: low carbon - carbon content generally less than 0.25 %, such as 10, 20 steel; in the carbon - carbon content is generally between 0.25 to 0.60%, such as 35, 45 steel; high-carbon steel - carbon content is generally greater than 0.60%. Such steel is generally not used to make steel Liaocheng Polygram Pipe Manufacturing Co., assure you: Miho service: quality assurance to ensure time to ensure that the number of service purposes: a strong, quality products, low prices, excellent service .
