Polishing methods of corten steel

Do you know the polishing methods of corten steel weathering steel? Today, we will make a brief introduction of this technology.
1. Mechanical polishing
 
The advantage is that the weathering steel of corten steel has good flatness and high brightness after processing. Its shortcomings are high labor intensity and serious pollution, and the complex corten steel weathering steel cannot be processed, and its gloss cannot be consistent, the gloss is not long, and it is stuffy and rusty. It is more suitable for simple processing of corten steel weathering steel.
 
2. Chemical polishing
 
The advantage is that the processing equipment investment is small, and complex parts can also be polished, and 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 required, and heating is difficult. It is suitable for processing small batches of complex corten steel weathering steel and small pipes with low brightness requirements.
 
3. Electrochemical polishing
 
The advantage is that the mirror gloss remains long, the process is stable, the pollution is low, the cost is low, and the corrosion resistance is good. Its shortcomings are high pollution prevention, large one-time investment in processing equipment, tooling and auxiliary electrodes for complex parts, and cooling facilities for mass production. Suitable for mass production of corten steel weathering steel, mainly used in high-grade corten steel weathering steel, export corten steel weathering steel, tolerance corten steel weathering steel, its processing technology is stable and easy to operate.
