In for a variety of stainless steel products processing a333 grade 6 pipe production, 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, cause in the presence of corrosive medium issued by biochemistry corrosion and electrochemical corrosion and rust.
Fine polishing the passivation for stainless steel surface x60 line pipe 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, 316l stainless steel pipe 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 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 x70 line pipe 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.
