Liaocheng Qingguo precision steel tube answer; 45 # precision steel tube and mirror tube although both belong to the category of precision steel tube, but they have some differences.
1. Different materials: 45# precision steel tube material is carbon structural steel, while the mirror tube can have a variety of materials, such as stainless steel, copper and so on.
2. Different production processes: 45# precision steel tubes can be made by hot rolling, cold drawing, deep hole machining, etc.; while the mirror tube needs to be polished, pickled and other treatment processes, and then finally electrolytic polishing or mechanical polishing in order to get a high surface quality.
3. Surface treatment is different: 45 # precision steel tube surface is usually coated with antirust paint and other treatment measures to avoid oxidation. Mirror tube in the surface treatment is more focused on ensuring the high gloss and flatness of its surface.
4. Different application scenarios: 45# precision steel tubes are mainly used in machinery, instruments, automobiles and other fields, while mirror tubes are mainly used in electronics, medical, food and other fields that require high surface quality.
In short, although 45# precision steel tubes and mirror tubes belong to the category of precision steel tubes, there are some differences in material, production process, surface treatment and application scenarios.
