Precision steel pipe is mainly used to produce pneumatic or hydraulic components because of its advantages such as no oxide layer on the inner and outer walls, high pressure, no leakage, high precision, high finish, no deformation in cold bending, flatness and no cracks. As a cylinder or an oil cylinder, it can be a seamless tube. The chemical composition of cold drawn precision steel pipe is carbon, silicon, Si, manganese, sulfur, phosphorus, phosphorus and Cr.. The popularization and application The so-called high-precision cold-drawn pipe is characterized by strict internal and external diameter accuracy (tolerance range), good surface finish, good roundness, uniform wall thickness. Some or exceed the requirements of standard GB and standard ISO434/i-1980
2011年10月，美国应美国钢铁公司和美国钢铁工人联合会的请求，提交了反补贴案。当时，中国官员说，他们盲目地指责从中国进口产品倾销或补贴，缺乏事实依据，中国坚决反对这种做法。
对于高碳钢，正火可以重组渗碳体，促进球化。对于截面变化剧烈的大型精密钢管或铸钢件，可以采用正火代替淬火，也可以采用变形和开裂倾向，或者可以制备淬火组织。精密钢管的淬火、修复部分会受到正火和过热的影响，从而发生再硬化。
