What is the reason for the corrosion of stainless steel castings?
1. On the surface of the stainless steel plate, there are additions of smoke and dust containing other chemical elements, or oak metal material particles. In cold, humid air, water that condenses between the accessory and the stainless steel plate connects the two to a microcharge. The battery causes electrochemical corrosion and damages the protective film. This is called an electrochemical reaction.
2. The surface of the stainless steel plate adheres to the organic compound juice (vegetables, soup noodles, phlegm, etc.), which forms organic substances in the presence of water and oxygen, and the organic substances corrode the metal surface. For a long time.
3. Acid, alkali and acid Acid chemicals (such as edible alkali and lime slurry scattered on the interior decoration wall) adhere to the surface of the stainless steel plate, causing partial corrosion.
4. Environmentally polluted air (air rich in sulfate, carbon monoxide, sulfur oxide, etc.) produces hydrochloric acid, sodium cyanide, and glacial acetic acid when it encounters condensed water, causing chemical corrosion.Fenghua Xinke Precision Casting Co., Ltd is a enterprise specializing in the manufacturing of Silica Sol Castings,Lost Wax Investment Castings,Coated Sand Castings and finished products in stainless steel,carbon steel and low alloy steel.
