There are many surface treatment processes for stainless steel, such as cleaning, degreasing, derusting, passivation, pickling, rust prevention, polishing, electroplating, electrophoresis, etc. Each stainless steel product manufacturer will choose different surface treatment according to the needs of its own production process. the way. In recent years, the more mature and extensive processes used have surface treatment processes such as stainless steel pickling passivation and stainless steel electrolytic polishing. However, many friends are still not very clear about the difference between stainless steel pickling passivation and electrolytic polishing. In this way, we will make a brief introduction so that everyone can understand and understand.

1. Stainless steel pickling passivation: The whole stainless steel is immersed in the stainless steel pickling passivation solution until the surface of the stainless steel piece is completely uniform silver white, and then the workpiece is taken out and rinsed with clean water. Most stainless steel products manufacturers with pickling passivation requirements are required to remove the surface soldering, high temperature oxide scale, and make the surface color of the stainless steel parts uniform and beautiful. The scope of application of this process is relatively wide: for example: stainless steel chemical pipeline treatment, stainless steel welded parts pickling treatment, stainless steel valve cleaning treatment. Because stainless steel pickling passivation solution can be recycled repeatedly, does not evaporate, does not volatilize, no yellow smoke and hydrogen embrittlement phenomenon, so the operating environment is good, and no special equipment is needed, because it is favored by the majority of stainless steel products manufacturers.
2, stainless steel electrolytic polishing: the stainless steel needs to be polished on a professional hanger, and then the electro-polishing equipment is turned on, while adjusting the power supply voltage, and then the fixed stainless steel parts are immersed in electricity and heated to 75 degrees of electrolysis In the liquid, the general time is 1-3 minutes. After the surface is bright, the workpiece can be taken out and rinsed. The brightness of the watch can be adjusted and controlled according to different requirements of different manufacturers. The surface of the stainless steel workpiece after electrolytic polishing has an absolutely uniform brightness and a fine effect, and the surface gloss can reach an 8K mirror effect. And lasting light as new, never peeling off. At the same time, this process can be applied to any shape of stainless steel products. All the common 200 series, 300 series, 400 series stainless steel surface polishing, high production efficiency, low cost, no pungent smell, good operating environment, is an alternative to traditional machinery and hand polishing The best choice.
Through the above brief introduction, I believe that everyone has a certain understanding of the difference between stainless steel pickling passivation and electrolytic polishing. In fact, the stainless steel surfaces treated by these two processes are very beautiful.
