Production introduction

After hot working, machining or standing for a certain period of time, stainless steel will form a black or gray scale on the surface. Its main components are Cr2O3, NiO and very insoluble FeO and Cr2O3. Their existence affects the appearance quality on the one hand. On the one hand, it also affects the performance of the product, so take appropriate measures to remove it. There have been many reports on surface treatments such as scale removal and finishing of stainless steel. As a mature surface treatment method, stainless steel polishing has been widely used, and polishing can further improve the corrosion resistance and brightening effect of stainless steel.

Comparison of advantages and disadvantages of three simple polishing methods for stainless steel
1.Mechanical polishing:

The advantage is that the processed parts have good flatness and high brightness. The advantages are that the labor intensity is high, the pollution is serious, and the complicated parts cannot be processed. And its gloss can not be consistent and the gloss retention time is not long.

2. Chemical polishing:

The advantage is that the processing equipment has less investment, the complicated parts can be thrown, the speed is fast, the efficiency is high, and the corrosion resistance is good. The disadvantage is that the brightness is poor, there is gas overflow, ventilation equipment is needed, and heating is difficult. It is suitable for processing small batches of complex parts and small parts with low brightness requirements.

3. Electrochemical polishing:

The advantage is that the mirror gloss remains long, the process is stable, the pollution is less, the cost is low, and the corrosion resistance is good. Processing equipment has a large investment at one time, complex parts require tooling and auxiliary electrodes, and mass production requires cooling facilities. Suitable for mass production, mainly used in high-grade products, export products, tolerance products, stable processing technology and simple operation.


Packing

Standard exported packing by wooden pallets or iron steel as photos. Eye to Sky and Eye to Sides package are both acceptable.
