不銹鋼酸洗處理的目的是以除去高溫焊接，熱處理或熱加工后不銹鋼表面的氧化皮。同時(shí)也可以消除了紅銹腐蝕的鋼或鐵或鋼顆粒污染物。請注意,酸洗后如果沒有清洗干凈表面的酸液，那么表面很快就會開始生銹腐蝕。導(dǎo)致在下面的鋼表面層的耐腐蝕性降低。

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.

不銹鋼酸洗工藝可以適用于所有200、300、400系列不銹鋼的表面處理。所有酸洗操作導(dǎo)致金屬表面會除去雜質(zhì)的同時(shí)稍有一點(diǎn)尺寸改變，因此，其結(jié)果是在一定程度上一個(gè)消光的視覺亮度或許也是一種顯著減少尺寸。

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.

在真空中的熱處理或一個(gè)良好的受控氣氛，例如光亮退火，消除了需要進(jìn)行酸洗，通常會使得不銹鋼得到一個(gè)更好的光潔面。

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.

不銹鋼酸洗的還有其他是去除不銹鋼表面的氧化膜.焊斑.銹點(diǎn).不銹鋼表面酸洗后生成一層致密的氧化膜，這道工序叫酸洗鈍化。這層膜是不銹鋼在一般介質(zhì)中不生銹、腐蝕的關(guān)鍵，因此不銹鋼不一定非要酸洗，只有在表面有氧化皮的情況下才需要。

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.

不銹鋼酸洗時(shí)常是和鈍化聯(lián)系在一起，一般需要酸洗的不銹鋼一定要鈍化，因?yàn)樗嵯春蟊砻鏇]有形成鈍化膜或者形成鈍化膜的厚度很薄，起不到什么作用，必須增加后續(xù)的鈍化工藝，在不銹鋼表面形成和完善鈍化膜，從而達(dá)到鈍化的效果。

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.
