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

Can be roughly divided into:hot-rolled seamless steel pipe, cold-rolled seamless steel pipe and precision seamless steel pipe. Overall:the advantages of seamless steel pipe are high pressure resistance, good toughness, long pipe section and few interfaces.
Cold-rolled sheet steel is produced from hot-rolled sheet with additional processing steps such as pickling, cold reduction, annealing and temper rolling. Cold-rolled steel is a product that has been cold reduced, as opposed to hot-rolled, in order to impart specific mechanical properties, surface finish, gauge tolerance and strip shape.
