Stainless steel coil is not only strong corrosion resistance, but also light weight, therefore, is widely used in the automobile manufacturing industry, such as the car shell needs a large number of stainless steel coil, according to statistics, a car needs about 10-30 kg of stainless steel coil, and the United States car needs 40 kg of stainless steel coil. Now some international brands of cars are beginning to use stainless steel coil as the structural material of the car, which can not only greatly reduce the weight of the vehicle, but also greatly improve the service life of the car. In addition, stainless steel coil in buses, high-speed rail, subway and other aspects of the application is more and more extensive.

Stainless steel rolls are mostly whole when they go out of the factory, mainly for convenient transportation; In the hands of our stainless steel processing factory, in order to facilitate processing and manufacturing, we will use professional stainless steel flattening equipment to open the whole volume of stainless steel. This process is called flattening.

Although both 301 and 304 stainless steels use iron as a major component, there are several key differences in chemical composition between the two alloys, as shown in the table above, and many compounds in both steel alloys have the same end-capping values. However, grade 304 stainless steel obtained more chromium and nickel than grade 301. This tends to make grade 304 stainless steel more expensive than grade 301.

There are chloride ions in the use environment. Chloride ions are found in salt, sweat, seawater, sea breezes, and soil. Stainless steel in the presence of chloride ions in the environment, corrosion is fast, even more than ordinary mild steel. So there are requirements for the use of stainless steel environment, and the need to often wipe, remove dust, keep clean and dry. (That would give him a "misuse.") The United States has an example: an enterprise uses an oak container to contain a solution containing chloride ions. The container has been in use for nearly a hundred years. In the 1990s, it planned to replace it, but the oak material was not modern enough and stainless steel was used.

Statistics from the Stainless Steel Branch of China Special Steel Enterprise Association show that in 2020, China's crude stainless steel production was 30.139 million tons, an increase of 739,400 tons, an increase of 2.51%, of which Cr-Ni steel (300 series) was 14.37,600 tons, an increase of 887,400 tons, an increase of 6.58%, accounting for 47.71%; Cr steel (400 series) 5,925,500 tons, an increase of 422,400 tons, an increase of 7.68%, accounting for 19.66%; Cr-Mn steel (200 series) 9,643,200 tons, down 589,900 tons, down 5.68%, accounting for 32.00%. In addition, in 2020, China's duplex stainless steel production reached a new high of 191,400 tons, an increase of 10,500 tons, an increase of 5.8%, accounting for 0.63%.

The corrosion resistance of stainless steel mainly comes from the formation of a dense protective layer on its surface after the chromium element in it reacts with oxygen. The role of pickling is to make it happen in advance of this reaction, in order to improve the corrosion resistance of stainless steel pipe, pickling process will remove the oil attached to the surface of the pipe and other substances contaminated in the production. The inner and outer surface of the pipeline is rough and easy to be attached by suspended impurities.
