What is Atmospheric Corrosion of Stainless Steel Plates

The atmospheric corrosion resistance of stainless steel basically varies with the chloride content in the atmosphere. Therefore, it is extremely important for the price of 304 stainless steel to be close to the sea or other sources of chloride pollution to the corrosion of stainless steel. A certain amount of rainwater is only important if it has an effect on the chloride concentration on the steel surface.

Rural environment 1Cr13, 1Cr17 and 304 stainless steel plate prices Austenitic stainless steel can be adapted to various uses without significant changes in appearance. Therefore, the stainless steel used in rural exposure can be selected according to price, market availability, mechanical properties, fabrication and processing properties and appearance.

Industrial environment In an industrial environment without chloride pollution, 1Cr17 and austenitic stainless steel can work for a long time, basically keep no rust, and may form a fouling film on the surface, but when the fouling film is removed , but also maintains the original bright appearance. In industrial environments with chlorides, stainless steel will corrode.

In the marine environment, 1Cr13 and 1Cr17 stainless steel will form a thin rust film in a short period of time, but the price of 304 stainless steel will not cause significant dimensional changes. Austenitic stainless steels such as 1Cr17Ni7, 1Cr18Ni9 and 0Cr18Ni9 , some rust may occur when exposed to the marine environment. Rust is usually shallow and can be easily removed. 0Cr17Ni12M02 molybdenum-containing stainless steel is basically corrosion-resistant in marine environments. In addition to atmospheric conditions, the price of 304 stainless steel plate has two other factors that affect the atmospheric corrosion resistance of stainless steel. That is, the surface state and manufacturing process. Finishing grade affects the corrosion resistance of stainless steel in chloride environments. Matte surfaces (matte surfaces) are very sensitive to corrosion. That is, normal industrial finishing surfaces are less susceptible to rust. Surface finish level also affects dirt and rust removal. It is easy to remove dirt and rust from highly finished surfaces, but difficult to remove from matte surfaces. For matte surfaces, frequent cleaning is required to maintain the original surface condition
