Description
technical field [0001] The invention relates to the field of iron and steel manufacturing, in particular to a stainless steel strip for an electronic device casing. Background technique [0002] The advancement of electronic technology and the improvement of people's lives have made mobile phones, tablet computers, MP4, navigators, e-books, mobile TVs and flat-panel TVs and other electronic devices a large number of people's lives and work, bringing convenience and fun to people. At present, people not only require powerful functions for the above-mentioned various electronic devices, but also hope that they have a beautiful appearance and a good surface texture. Therefore, the processing precision and roughness of the shell surface of the electronic device are highly required. [0003] At present, 304 austenitic stainless steel is commonly used in the manufacture of housings of electronic devices, especially cold-rolled sheets, because cold-rolled sheets have relatively goo...
