Cold-drawn or cold-rolled precision seamless steel tubes

Cold-drawn or cold-rolled precision seamless steel tubes (GB3639-2000) are cold-drawn or cold-rolled precision seamless steel tubes for mechanical structures and hydraulic equipment with high dimensional accuracy and good surface finish. High-precision cold-drawn precision steel pipe is a new high-tech energy-saving product. The promotion and application of high-precision cold drawn precision steel tubes saves steel, improves processing efficiency, and saves energy. The main materials and mechanical properties of precision seamless steel tubes: The raw materials used in the precision tube department are mainly produced by Shanghai Baosteel St35, St37.4(10#), and St45. (20#), St55(35#), Ck45(45#), St52(16Mn) and the like. The mechanical performance and technical performance of the steel pipe produced by the Precision Pipe Department are excellent. The steel pipe can withstand high pressure and impact, and is particularly suitable for hydraulic machinery and auto parts industries. The steel tube can be cold-formed at any angle and can be expanded or flattened without cracks. It is suitable for industries that require various bending deformations.
