The corrosion of stainless steel corrosion resistant pumps is usually shallow and can be easily removed. 0Cr17Ni12M02 molybdenum containing stainless steel is basically corrosion-resistant in the marine environment. In addition to atmospheric conditions, there are two other factors that affect the corrosion resistance of stainless steel, namely, surface state and fabrication process. The finishing level affects the corrosion resistance of stainless steel in the environment with chlorides. The non - optical surface (wool surface) is very sensitive to corrosion, that is, the normal industrial finishing surface of the stainless steel corrosion resistant pump is less sensitive to corrosion. The level of surface finishing also affects the removal of dirt and rust. It is easy to remove dirt and rust from a highly refined surface, but it is difficult to remove it from a surface without light. For non - optical surfaces, more frequent cleaning is needed if the original surface state is to be maintained. Stainless steel chemical pump
Corrosion resistance pump performance of stainless steel:
1. The atmospheric corrosion resistance of stainless steel [1] is basically changed with the content of the chloride in the atmosphere.
2. Fresh water can be defined as acidity, salt or brackish, from rivers, lakes, ponds, or wells.
3, acid water refers to the polluted natural water precipitated from ore and coal. Because of its strong acidity, its corrosiveness is much stronger than that of natural fresh water.
4. The corrosion characteristics of salt water are often in the form of pitting.
5, the metal embedded in the soil depends on the weather and other factors, in a complex state of change at any time.
6. The ferritic stainless steel and austenitic stainless steel with no less than 14% chromium have excellent resistance to nitric acid corrosion.
7, standard stainless steel grades are rarely used in sulphuric acid solutions because they can be used in a narrow range.
