我們生活中使用的不銹鋼制品的東西很多，廚房用品是大家常接觸到的。有些電梯門套、推拉門也會用到濟南不銹鋼板材進行加工后使用。為了讓這些材料正常投入使用，針對不銹鋼本身出現腐蝕的方法我們可以提前采取方法預防。
There are many stainless steel products used in our life, and kitchen supplies are often touched by everyone. Some elevator door jambs and sliding doors will also be processed with Jinan stainless steel plate. In order to put these materials into normal use, we can take measures to prevent the corrosion of stainless steel in advance.
不銹鋼制品在人們眼里都是很堅硬的材料，所以認為不銹鋼應該不會有腐蝕的情況，但是不銹鋼型材在自然狀態下，也是會出現一些問題的，
Stainless steel products are very hard materials in people's eyes, so it is considered that stainless steel should not have corrosion, but stainless steel profiles will also have some problems in natural state,
預防不銹鋼出現點蝕的正確方法
Correct method to prevent pitting corrosion of stainless steel
達到點蝕造成的重量損失.大；對于更稀的溶液，點蝕速率隨溫度升高而增加。例如在濃度為4％～10％氯化鈉的溶液中。.高溫度出現在較高的溫度。防止不銹鋼點蝕的方法：防止鹵素離子的濃度。*氧氣或氧化液的均勻性，攪拌溶液，防止溶液處于靜止狀態。增加氧氣的濃度，或除去氧氣。提高pH值。與中性或酸性氯化物相比，明顯的堿性氯化物溶液引起的點蝕較少，或不存在（氫、氧離子起緩蝕作用）以防止氯離子吸附引起的腐蝕。采用陰極腐蝕保護。在盡可能低的溫度下工作。在腐蝕性介質中加入鈍化劑。在許多介質中，低濃度的硝酸鹽或鉻酸鹽可以很好地防止離子優先吸附在金屬表面。
Achieve the weight loss caused by pitting corrosion Large; For thinner solutions, the pitting rate increases with the increase of temperature. For example, in a solution with a concentration of 4% ~ 10% sodium chloride High temperature occurs at higher temperatures. Methods to prevent pitting corrosion of stainless steel: prevent the concentration of halogen ions* The uniformity of oxygen or oxidizing solution, stir the solution to prevent the solution from being at rest. Increase the concentration of oxygen or remove oxygen. Increase pH. Compared with neutral or acidic chlorides, the obvious alkaline chloride solution causes less pitting corrosion, or there is no (hydrogen and oxygen ions play a corrosion inhibition role) to prevent the corrosion caused by chloride ion adsorption. Cathodic corrosion protection is adopted. Work at the lowest possible temperature. Add passivator in corrosive medium. In many media, low concentration of nitrate or chromate can well prevent ions from preferentially adsorbing on the metal surface.
通過不銹鋼加工廠家分享上面的內容我們能夠了解到不銹鋼制品出現腐蝕的原因以及解決方法，大家在使用時也一定要注意進行預防，以便后期更好使用。
By sharing the above contents with stainless steel processing manufacturers, we can understand the causes and solutions of corrosion of stainless steel products. We must also pay attention to prevention during use, so as to better use in the later stage.
