Stainless Steel Surface Treatment And Product Processing Common 8 Major Problems

Stainless steel plate application development prospects will be more and more widely, but the application of stainless steel plate development to a large extent determine its surface treatment technology development. 304 stainless steel tube

Stainless steel surface treatment and product processing process there are eight major problems

1, weld defects: weld defects are more serious, the use of manual mechanical grinding method to make up, resulting in grinding traces, resulting in uneven surface, affecting the appearance.

2, the surface is inconsistent: only pickling passivation of the weld, but also cause uneven surface, affecting the appearance.

3, scratches difficult to remove: the overall pickling passivation, can not be processed in the process of removing all the scratches, and can not remove due to scratches, welding splash and adhere to the surface of stainless steel carbon steel, splash and other impurities , Resulting in the presence of corrosion medium in the presence of chemical corrosion or electrochemical corrosion and rust.

4, polished and passivated passivation uneven: hand-polished after pickling passivation treatment, the larger the workpiece, it is difficult to achieve uniform uniform treatment effect, can not be ideal for the uniform surface. And the cost of work, accessories are also higher costs.

5, pickling ability is limited: pickling passivation paste is not a panacea, the plasma cutting, flame cutting and production and black oxide, more difficult to remove.

6, for the factors caused by more serious scratches: in the lifting, transportation and structural processing, bumping, dragging, hammering and other human factors caused by more serious scratches, making the surface treatment more difficult, but also after treatment to produce corrosion The main reason.

7, equipment factors: in the profile, sheet bending, bending process, resulting in scratches and creases are also the main reason for the treatment of corrosion.

8, other factors: stainless steel raw materials in the procurement, storage process, due to lifting, the transport process of the bumps and scratches are more serious, but also one of the causes of corrosion.
