Stainless steel flanges can also rust in certain environments
When we do not understand stainless steel, we generally think that stainless steel is not rust, in daily life we common in the home stainless steel products such as food grade 304 stainless steel drinking cup, wash basin, stainless steel tableware, stainless steel kitchen utensils, we see these stainless steel products are not rust, so blindly think that other with stainless steel production products will not rust.Since I went to work in Shanxi Haokun Flange Group Co., Ltd their cognition has changed, the company's flange raw materials also have stainless steel material, after the continuous learning of stainless steel flange knowledge, stainless steel flange will also be born Rust.Below we will detailed understanding of the daily life of several stainless steel flange rust: 1, stainless steel flange surface with dust containing other metal elements of attachment or heterogeneous metal particles, in the humid air, attachments and condensate between stainless steel flange, the two into a micro battery, caused the electrochemical reaction, protective film was damaged, called electrochemical corrosion.2. The stainless steel flange surface adheres to organic juice (such as melon vegetables, noodle soup, phlegm, etc.), long-term stainless steel flange in the case of water and oxygen, constitute organic acid, organic acid corrosion to the metal surface for a long time.3, Stainless steel flange table Facial adhesion contains acid, alkali, salt, class substances (such as the decoration wall of alkali water, lime water splash), causing local corrosion.4, in polluted air (such as contains a large number of sulfide, carbon oxide, nitrogen oxide atmosphere), meet condensate, form sulfuric acid, nitric acid, acetic acid, cause chemical corrosion, the above conditions can cause the damage of stainless steel flange surface protective film rust, so, to ensure that the metal surface permanent bright, not rust.
