Abstract

The invention discloses an austenite stainless steel thin strip for an electronic product shell. The austenite stainless steel comprises the following components by weight percent: 0.06-0.08% of C, 14.5-16.5% of Cr, 11.0-13.0% of Ni, 1.4-1.8% of Mn, 0.3-1.0% of Si, 0.5-0.8% of Mo, 0.3-0.6% of Nb, 0.001-0.005% of B, 0.010-0.060% of Al, 0.05-0.20% of N, no more than 0.03% of P, no more than 0.005% of S, no more than 0.0050% of O and the balance of Fe and inevitable impurities. The Ni-bal% range of the stainless steel is 0.5-1.5 and Ni-bal% is calculated according to the following formula: Ni-bal% = Ni% + 30(C% + N% + B%) + 0.5Mn%-1.5(Cr% + 1.5Si% + Mo% + 0.5Nb%) + 8.5%.

Description

technical field [0001] The invention relates to the field of stainless steel alloys, in particular to an austenitic stainless steel thin strip for electronic product casings. Background technique [0002] Along with the raising of people's living standard, electronic devices such as mobile phone, PDA (personal digital assistant, personal digital assistant), MP3 and palmtop computer enter people's life and work in a large number, bring 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 good surface quali...
