Problems solved by technology

Although this kind of stainless steel fiber can be drawn very thin, after being drawn to a certain extent, the overall performance of the fiber filament is not high, and it is brittle and easy to break.
The existing production process of stainless steel fiber is: tube loading, electroplating, drawing, annealing, cleaning, the stainless steel fiber processed by this process, the electroplating voltage is above 10-12V, the line speed is high, and the wire is easy to break when pulled. The pass processing rate is small, the number of annealing is large, and the chemical elements of raw materials change greatly, so the comprehensive performance is not high

Description

technical field [0001] The invention belongs to the field of metal material processing, and relates to an alloy material for a load-bearing grid of a high-strength shelf and a treatment process thereof. 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. An invention patent named "Bundled Drawn Stainless Steel Fiber" with application number: 02814697.2 discloses that its composition contains iron and the following components (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 being drawn to a certain extent, the comprehensive performance of the fiber filament is not high, and it is b...
