Surface treatment of stainless steel bars

The production process of stainless steel bar is more, the product is bundled neatly, and the surface of stainless steel rod is also very beautiful. In the production, the manufacturer is how to deal with the surface of stainless steel bar? This article to understand it.

Attention should be paid to all aspects of the production of stainless steel bars, grinding and surface processing of stainless steel bars need to be careful and meticulous. With the use of stainless steel bars more and more widely, more manufacturers will have larger orders, we must not be careless, we must deal with stainless steel rod surface. The surface treatment of stainless steel bars is the first process of polishing, which is part of the polishing process.

In fact, there are many techniques for the surface treatment of such stainless steel bars. If there is a defect on the surface of the stainless steel bar, it must be polished in manual way at this time, and then the processing decision of the bar is made. Now stainless steel bars have been applied to many fields, and their chemical properties are different from those of other stainless steels.

For stainless steel bar surface treatment, first to detect the workpiece in all directions, if the quality is not qualified, such as butt joint is uneven, the solder joint uneven depth, it is best to rework processing, until the stainless steel rod workpiece to determine the defect after grinding. In the process of grinding stainless steel rod, we need to carefully remove the solder joints and scratches left by welding, so that the surface treatment is clean. There are two kinds of grinding: rough grinding and fine grinding. After grinding, the surface of the stainless steel rod will be very bright, and the trace of the seam can be completely eliminated. After grinding, the stainless steel bar work piece shows the effect of approaching the mirror surface.

Polishing is also a process for treating the surface of stainless steel bars. There are generally three methods, namely mechanical polishing, chemical polishing and electrochemical polishing. Mechanical polishing is especially suitable for polishing large pieces, small pieces are difficult to achieve very good results, and are suitable for batch production. The advantage of this method is that it can be very good surface treatment, but the drawback is that the cost of investment is higher, the intensity of labor is relatively large, in addition to serious pollution problems, so many manufacturers are not optimistic.

Chemical polishing is the same, the cost is low, without the use of large machinery and equipment, flexible investment, polishing speed is also very fast, but the drawback is that the brightness of polishing is not good enough. The electrochemical polishing process is more stable, easy to operate, and lower investment costs, pollution is small, as long as a one-time investment after the cost is no longer necessary, and now most enterprises use this.
