Hot rolled stainless steel and cold rolled stainless steel are the forming process of section steel or steel sheet.Cold rolling and hot rolling are different processes.Stainless steel cold rolled plate is simply a relatively thin steel plate, between (0.31-4.0mm), 4mm more than there is rarely cold rolled plate, surface 2B surface, bright.Stainless steel hot rolled plate is the thicker steel plate that we usually say, thin plate also has hot rolled plate, the surface is industrial face, not bright, thick plate (thickness is greater than 4mm) and thin plate (thickness is 0.5~4mm) two kinds.

Sometimes we assume something is right, but there are a lot of things in life that are not as right as we seem to think. Stainless steel will not rust?

1.The surface of the stainless steel plate offer the dust containing other metal elements, or heterogeneous metal particles such as attachments, appeared in the humid air, its attachments and condensed water between direct and stainless steel plate, when happen between micro batteries, will cause a series of chemical reactions, the protective film on the surface of the stainless steel plate can also severely damage, so we can call the electrochemical corrosion.

The stainless steel coil has the ability to withstand general corrosion similar to the unstable nichrome 304. Prolonged heating in the temperature range of chromium carbide may affect alloys 321 and 347 in harsh corrosive media. Mainly used in high temperature applications, high temperature applications require strong sensitization of materials to prevent intergranular corrosion at lower temperatures.

304 stainless steel plate surface is beautiful and the possibility to use diversification, corrosion resistant performance is good, than ordinary steel long durable 304 stainless steel corrosion resistance is good High strength, and therefore the possibility of using big plate, high temperature oxidation resistance and high strength, thus able to fight a fire Room temperature processing, namely easy to plastic processing, because need not surface treatment, so simple, simple maintenance, cleaning, high degree of finish Good welding performance.

Primary products: 304/304L stainless steel sheet, steel plate, 316/316 l stainless steel plate, 310 s stainless steel plate, steel, 201 stainless steel sheet, steel, 321 stainless steel plate, steel.

Generally speaking, the square tube of the finished product that has been processed has a small degree of tortuosity, or it depends on the proofreading of the machine. Generally, to eliminate the bending of the square tube, it is necessary to pass the cold straightening, and the square tube The bending may be due to the fact that the mill is not adjusted for adjustment. Therefore, the remaining force in the rolling is formed by cooling or the like along the section and length of the pipe. Therefore, it is not possible to use a rolling mill to directly obtain a very straight pipe, and it is necessary to pass the cold straightening pipe to satisfy the non-bending of the pipe.
