Application of seamless steel pipe - sellsteels

Generally, the seamless pipe is made of high-quality carbon steel such as 10, 20, 30, 35, 45, etc., such as low-alloy structural steel such as 16Mn and 5MnV, or hot-rolled or cold-rolled steel of 40Cr, 30CrMnSi, 45Mn2, and 40MnB. Carbon Steel - Seamless Rolled RingsAbove and below this level, machinability is generally lower for hot-rolled steels. Standard wrought-steel compositions (for both carbon and alloy steels) are designated by an AISI or SAE four-digit code, the last two digits of which indicate the nominal carbon content. The carbon-steel grades are:10xx:Plain carbon; 11xx:Resulfurized
