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.
