不锈钢酸洗处理的目的是以除去高温焊接，热处理或热加工后不锈钢表面的氧化皮。同时也可以消除了红锈腐蚀的钢或铁或钢颗粒污染物。请注意,酸洗后如果没有清洗干净表面的酸液，那么表面很快就会开始生锈腐蚀。导致在下面的钢表面层的耐腐蚀性降低。

The purpose of the stainless steel pickling treatment is to remove the oxide skin of the stainless steel surface after high temperature welding, heat treatment or hot processing.It can also eliminate steel or iron or steel particles.Please note that if no acid is cleaned, then the surface soon begins to rust and corrode.This results in reduced corrosion resistance in the steel surface layer below.

不锈钢酸洗工艺可以适用于所有200、300、400系列不锈钢的表面处理。所有酸洗操作导致金属表面会除去杂质的同时稍有一点尺寸改变，因此，其结果是在一定程度上一个消光的视觉亮度或许也是一种显着减少尺寸。

Stainless steel pickling process can be suitable for all 200,300,400 series stainless steel finishes.All pickling operations cause the metal surface to remove impurities, so the result of a reduced visual brightness may also be a significant reduction in size.

在真空中的热处理或一个良好的受控气氛，例如光亮退火，消除了需要进行酸洗，通常会使得不锈钢得到一个更好的光洁面。

Heat treatment in vacuum or a good controlled atmosphere such as light annealing eliminates the need for pickling, often giving a stainless steel a better finish.

不锈钢酸洗的还有其他是去除不锈钢表面的氧化膜.焊斑.锈点.不锈钢表面酸洗后生成一层致密的氧化膜，这道工序叫酸洗钝化。这层膜是不锈钢在一般介质中不生锈、腐蚀的关键，因此不锈钢不一定非要酸洗，只有在表面有氧化皮的情况下才需要。

Stainless steel pickling has other oxide films that remove the stainless steel surface. Welding spot. Rust point. Stainless steel surface after pickling to produce a dense oxide film, this process is called pickling passivation.This layer of film is the key to stainless steel not to rust and corrosion in general media, so stainless steel does not have to be pickling, only in the case of oxidized skin on the surface.

不锈钢酸洗时常是和钝化联系在一起，一般需要酸洗的不锈钢一定要钝化，因为酸洗后表面没有形成钝化膜或者形成钝化膜的厚度很薄，起不到什么作用，必须增加后续的钝化工艺，在不锈钢表面形成和完善钝化膜，从而达到钝化的效果。

Stainless steel pickling is often associated with passivation, generally need pickling stainless steel must be passivation, because pickling surface did not form passivation film thickness is thin, play little role, must increase the subsequent passivation process, in the stainless steel surface formation and the perfect passivation film, so as to achieve the effect of passivation.
