In for a variety of stainless steel products processing production, a333 grade 6 pipe need to be on stainless steel surface processing. Influenced by various factors, and its surface may exist certain problems, such as there will be a weld defects, performance is likely a scratch, and fine polishing the effect not beautiful also easily lead to poor stainless steel surface.
Stainless steel surface processing, the severe weld defect is the stainless steel surface processing often meets, use manual mechanical polishing processing method to make up for, traces of grinding, the surface caused by uneven, affect beautiful. Surface does not agree the problem, only to pickling passivation of weld, also causes uneven surface, affect beautiful. To get rid of difficult overall pickling passivation, and machining process of various scratches cannot be removed, and also can't remove adhesion due to scratches, welding spatter on the surface of the stainless steel, carbon steel, the impurities such as splash, x60 line pipe cause in the presence of corrosive medium issued by biochemistry corrosion and electrochemical corrosion and rust.
Fine polishing the passivation for stainless steel surface processing is uneven, manual fine polishing after pickling passivation treatment, on the workpiece with larger area, it is difficult to achieve uniform processing effect, not the ideal uniform surface. And man-hour cost, material cost is higher also. Pickling passivation paste is not everything. There's mastercard for plasma cutting and flame cutting and production and black oxide coating, more difficult to eliminate. In the process of lifting, transportation, and structure, dragging, hammer knock against, serious scratches caused by human factors, such as harder to make surface treatment, but also the main reason of corrosion after processing.
Stainless steel decorative pattern plate there are two types, one is at the time of production, with rolling mill out, this kind of steel plate pattern is comparatively rigid, design also is fixed, but the thickness is relatively large, about 3 -- 6 mm, and to make 316l stainless steel pipe it produce decorative pattern, is the need to go through some process, such as stainless steel billet and strip rolling black volume to thermal annealing and pickling line, trimming machine, drawing machine, polishing line to cross line, hot rolled stainless steel decorative pattern.
At the same time, it also has a characteristic, which side is flat, one side is the decorative pattern, this pattern plate is usually applied to some high place to the requirement of temperature, such as railway, platform, etc., are all need to adopt the pattern plate, are more widely used.
Stainless steel decorative pattern of the second type is the common processing enterprises on the market, they because of the need of production, to buy hot rolled plate, and then through mechanical produce decorative pattern, it is usually a convex and concave side, is often used for decorative purposes.
In either stainless steel products, its corrosion resistance are all opposite, the same kind of stainless steel products, the purpose is the same, but if taken in the process of using product maintenance way and the method is different, so the probability of corrosion to occur in the stainless steel products is also different, generally speaking, often to correct cleaning and maintenance, the stainless steel products can reduce the risk x70 line pipe of corrosion to occur in the stainless steel. Either stainless steel or stainless steel pipe, stainless steel surface impurities attached words for a long time, over time, can lead to stainless steel corrosion occur. Therefore, in the process of using stainless steel products, especially for life or decoration in the field of stainless steel products, in use process, often must be clear on its surface, for example, stainless steel door, stainless steel panel lampblack machine, etc., all these need regular cleaning on the surface, it can remove the surface dirt and oil, effectively prevent the occurrence of corrosion of stainless steel plate, keep the appearance of the light and the service life of the product.
