Mechanical steel tube and precision steel tube are both types of steel tubes used for different applications, and the main differences between the two are: Manufacturing process: Mechanical steel tube is made by rolling and welding steel strips or plates, while precision steel tube is made by cold-drawing steel through a die, which results in a higher degree of dimensional accuracy and surface finish. Tolerance: Precision steel tube has tighter dimensional tolerances than mechanical steel tube, which makes it more suitable for applications where tight tolerances are required. Surface finish: Precision steel tube has a smoother and more consistent surface finish than mechanical steel tube, which makes it more suitable for applications where a high-quality surface finish is required. Application: Mechanical steel tube is commonly used in structural applications, industrial machinery, automotive industry, agricultural equipment, and sports equipment, while precision steel tube is commonly used in applications where dimensional accuracy, surface finish, and tight tolerances are critical, such as in the medical equipment, aerospace, and high-precision machinery industries. Overall, the main differences between mechanical steel tube and precision steel tube are the manufacturing process, tolerance, surface finish, and application, with precision steel tube being more suitable for applications where tight tolerances, high-quality surface finish, […] read more
