There are plenty of ways to clean stainless steel profiles, stainless steel toned bars, stainless steel circular bars, etc. which are provided to enhance the properties of s / s profile. Now we mainly bring in three common surface clean processes of stainless profile: passivation, pickling and degreasing.



1. Stainless steel passivation



The recommended surface just for this process must be iron-free. The existence of stainless steel particles to the surface of any flat iron, cast iron, low co2 steel, medium carbon steel as well as low alloy steel can promote pitting corrosion with "free" iron and s / s on its surface. That is the very serious problem, so passivation is used to treat metal and stainless steel. The principle purpose of stainless steel passivation is always to prevent stainless steel exterior oxidation and corrosion.



COUPLE OF. Stainless steel pickling



The purpose of stainless steel pickling treatment would be to remove oxide scales to the surface of stainless metal after high temperature welding, temperature treatment or hot operating. At the same time period, it can eliminate the particular contamination of steel or iron or steel particles that are corroded by red corrode. Please note that when there is no acid solution to scrub the surface after pickling, the surface will start to rust and corrode before long. The corrosion resistance belonging to the steel surface layer down below is reduced.



Stainless steel pickling process might be applied to all 2 HUNDRED, 300, 400 series of s / s surface treatment. All pickling operations result in the removal of impurities on the metal surface with a slight change proportions, so the result is to some extent a extinction of visual brightness can be a significant reduction bigger.



Heat treatment in vacuum or a superb controlled atmosphere, such because bright annealing, eliminates the demand for pickling, and usually gives metal a better finish.



3 OR MORE. Degreasing and degreasing of metal cleaning agent



The pretreatment of any technique of stainless steel surface medication must first remove grease, chopping fluid, paint compounds and also other lubricants, etc. before the surface heat treatment of metal parts or the final passivation treatment is often carried out. Stainless steel parts should also be further welded before degreasing to avoid pickup carbon at high temperatures.



Usually, stainless metallic profile cleaning agent (No. CA-Q03) is definitely chosen. It only needs 1-8 a matter of minutes to soak at room temperature to eliminate any oil pollution. You can actually operate and has lower labor intensity. It can be reused regularly and effectively reduce the expense of production. In cleaning experditions with other metals, the cleanliness rate might be increased through the usage of brushing, spraying or stirring procedures.



In addition to the particular above processes, such when: electroplating, anodic oxidation, sandblasting, painting like a professional, passivation, pickling, degreasing, rust removal etc ..
