Stainless steel plate is a kind of corrosion products is not easy, unless it's some serious condition actually not impossible to achieve in any products from corrosion, if our stainless steel plate from corrosion are likely to affect the normal use of it, so in order to avoid this situation and we need to do some preventive measures, the following we first to get to know what are the factors from corrosion of stainless steel plate?
A) electrochemical corrosion
Stainless steel plate caused by contact with carbon steel cut, x52 line pipe and form a galvanic corrosion medium after it can produce electrochemical corrosion. Pickling passivation result is bad, also makes the plate surface passivation membrane uneven or too thin, it is easy to produce electrochemical corrosion, cut, easy to rust material such as splash slag adhesion on the board, and form a galvanic corrosion medium, resulting in electrochemical corrosion. Pickling passivation cleaning not clean in pickling passivation of the residual liquid and chemical corrosion products, and sheet forming after electrochemical corrosion.
2) chemical corrosion
Under certain conditions some attached on the surface of the stainless steel plate, oil, dirt or later converted to acid, alkali, salt corrosion medium, react with some ingredients in plate, resulting in chemical corrosion caused by rust. Pickling passivation cleaning not clean enough to cause residual fluid collection, thereby directly sheet corrosion. Plate surface scratches, leading to the passivation film is destroyed, x56 line pipe so that the protection ability of the sheet has been reduced, easy to react and chemical medium, chemical corrosion and rust.
Stainless steel plate surface is smooth, high plasticity, toughness and mechanical strength, acid and alkali corrosion of gas, solution, and other media. It is a kind of alloy steel is not easy to rust, but not absolutely not rust. Stainless steel plate is weak media such as air, steam and water corrosion resistance of steel, acid steel plate is refers to the chemical etching media such as acid, alkali, salt corrosion of the steel plate. Stainless steel plate since the beginning of the 20th century, has a history of more than a century.
Stainless steel plate surface is smooth, high plasticity, toughness and mechanical strength, acid and alkali corrosion of gas, solution, and other media. It is a kind of alloy steel is not easy to rust, but not absolutely not rust.
The material of stainless steel tube on the market has a lot x60 line pipe of, such as 201, 304, 316 and so on, have a difference in price between the material of stainless steel pipe, said 201 stainless steel tube while material is not the best, but the advantage is that the price is low, by comparison is the performance-to-price ratio is high, so a lot of people use were made with 201 stainless steel frames, counters, etc.
Stainless steel frames, the general requirements of the counter surface is very bright, surface finish generally need to achieve 600 mesh, 800 mesh is even higher requirements. But ordinary 201 stainless steel tube surface finish at about 400 mesh, so the need for polishing processing again. And some of the poor quality of 201 stainless steel tube after polishing can appear the problems such as sand holes, sand holes; And after processing the surface of 201 stainless steel pipe corrosion resistant ability are influenced by a certain, rusting is likely to happen, and the problems after processing the surface of the pipe is not within the scope of warranty. Do other exhibition products not only polishing processing, also need other processing, such as bending, bending, etc.
So do the prop 201 stainless steel pipe must be refining furnace of raw materials, such as 201 stainless steel tube surface after machining is not easy to appear problem, if is the use of corrosive environment, such as hospitals, chemical plants, such as 201 stainless steel tube is likely to fall, need to use material 304 or better, but the shopping mall with 201 stainless steel tube is ok. The last one is to choose the manufacturers, because good manufacturer whether 201 stainless steel tube surface quality and processing technology will be protected.
