Abstract

The invention discloses a stainless steel. The stainless steel is characterized by comprising the following components represented by wt.%: 0.06-0.08% of C, 0.20-0.46% of Mn, 0.40-0.63% of Si, 20-40% of Ni, 40-60% of Cu, 4-10% of Al, 15-26% of Cr, 1-2% of Cu, 0.03-0.04% of S, 0.04-0.05% of P, and 67-81% of Fe. By adopting the technical scheme, the stainless steel wires disclosed by the invention are suitable for being subjected to drawing machining, the diameter of each wire can achieve 6 microns, the strength of each wire is greater than 16 Newton / square millimetre, and the elongation of each wire is 1.40%; the comprehensive performance of the finished products is greatly improved; and the defects that the original stainless steel wires cannot be drawn to be thin, and are brittle and easy to break are completely overcome.

Description

technical field [0001] The invention belongs to the field of metal processing, in particular to stainless steel and its manufacturing process. Background technique [0002] In the production and processing of stainless steel wire, sometimes the stainless steel wire needs to be processed very thin, and its comprehensive performance is required to be still strong and not easy to break. But existing stainless steel wire does not have such condition. According to the search by the inventor, the name is "stainless steel fiber material and processing technology and stainless steel fiber muffler core", the name is "bunch drawn stainless steel fiber", the application number is: 02814697.2, and the composition of its stainless steel fiber includes iron and the following Composition (expressed in wt.%): C<=0.05% , Mn≤5% , Si≤2% , 8%≤Ni≤12% , 15%≤Cr≤20% , Mo≤3% , Cu≤4 % , N≤0.05%, S≤0.03%, and P≤0.05%. Although this kind of stainless steel fiber can be drawn very finely, after be...
