STKM11A is the steel grade of Carbon Steel Pipe for mechanical structure. It is a Japanese grade corresponding to China's national standard Steel Pipe. Precision seamless pipe is a kind of high-Precision Steel Pipe material processed by cold drawing or hot rolling. Because the inner and outer walls of the precision steel pipe have no oxide layer, withstand high pressure without leakage, high precision, high finish, no deformation after cold bending, no expansion. Therefore, it is mainly used to produce pneumatic or hydraulic components, such as air cylinders or oil cylinders, which can be seamless pipes or welded pipes. The chemical composition of Precision Steel Pipes includes carbon C, silicon Si, manganese Mn , Sulphur S, Phosphorus P, Chromium Cr, compared with solid steel such as round steel, Seamless Steel Pipe has lighter weight when the bending and torsional strength is the same. It is an economical section steel and is widely used in the manufacture of structural parts and machinery Components.
