Corrosion resistance of stainless steel plate is not absolute, 316 stainless steel plate in stainless steel products on the market, almost all of the stainless steel plate and stainless steel pipe has certain corrosion resistance, the corrosion resistance of stainless steel is compared with the ordinary metal products, in addition, the corrosion resistance of stainless steel and stainless steel material, different material of stainless steel products, its corrosion resistance is different. Stainless steel believes that the corrosion resistance of stainless steel in addition to related to the material, and stainless steel products in the related content of chromium and nickel element, also related to whether the correct maintenance.
In either stainless steel products, its corrosion resistance are all opposite, the same kind of stainless steel products, the purpose is the same, but if taken in the process of using product maintenance way and the method is different, so the probability of corrosion to occur in the stainless steel products is also different, generally speaking, often to correct cleaning and maintenance, the stainless steel products can reduce the risk of corrosion to occur in the stainless steel. Either stainless steel or stainless steel pipe, stainless steel surface impurities attached words for a long time, over time, can lead to stainless steel corrosion occur. Therefore, in the process of using stainless steel products, especially for life or decoration in the field of stainless steel products, in use x52 line pipe process, often must be clear on its surface, for example, stainless steel door, stainless steel panel lampblack machine, etc., all these need regular cleaning on the surface, it can remove the surface dirt and oil, effectively prevent the occurrence of corrosion of stainless steel plate, keep the appearance of the light and the service life of the product.
Production is often with the help of dust venue, often with a lot of dust in air, they constantly fall on the surface equipment. They can use water to get rid of or alkaline solution. However, there is adhesion of dirt need high pressure water or steam to clean up.
Use flux for welding process with manual welding, flux core arc 316ti stainless steel welding and submerged arc welding, the welding process can leave fine flux grains on surface, ordinary cleaning method can't clear them away. These particles will be the source of corrosion, crevice corrosion mechanical cleaning methods to remove the residual flux must be used.
As standard A380 [3] notes if the rust test solution can't clear clean, all on the surface of the craft that equipment is not recommended, namely to produce human consumer direct contact surface using this test method. Relatively simple test method is exposed 12-24 hours in the water, check for a rusty spot. This kind of test sensitivity is poor, and time-consuming. These are test, not a cleaning method. If found to have iron exists, must use the introduction of the chemical and electrochemical methods to clean up.
