Type Classification of Stainless Steel

Sep. 16, 2020

Stainless steel can be divided into five categories: coils, plates, profiles, steel pipes and parts, the most important of which is coils and plates. Profiles are materials of various shapes made of plates, including angle steel, flat steel, I-beam, channel steel, and bar. Steel pipes mainly refer to Seamless Stainless Steel Pipes and welded pipes. The main difference lies in whether they are formed at one time. Parts mainly refer to pipe fittings, elbows and flanges and other small things.

The coil and the plate are actually the same, and the factory form is different. The coil is rolled one by one, and the plate is one by one. If the plate is shipped from the factory, it is also called the original plate. It is usually a thick plate. If it is thick, it cannot be rolled, generally if it is more than 16 mm, it cannot be rolled.

There are coils, plates, and often plates. The prices of coils and plates are different. If it is a purchase roll, it is calculated according to the actual weight, so the price is high, and the board is calculated according to the theory, the price is low, because there is a difference, such as 10mm thick may actually be 9.6mm, and there will be a price difference. .

Stainless Steel Plate are divided into hot rolling and cold rolling according to the rolling process of the rolling mill. Hot rolling is usually marked as NO.1, and cold rolling is marked as 2B or BA. For example, 304 is often a purchased plate, which means that the coil must be flattened by a machine, which is a flattening machine. It can be opened into different lengths through the flattening machine. If it is not a regular length, it is called a fixed opening, which means a fixed opening size, because customers often propose different length requirements according to actual needs. At this time, the roll becomes important. The board cannot meet the requirements.

Domestic cold rolling is generally below 3 mm, and hot rolling is generally above 3 mm. There are hot rolling and cold rolling for 3 mm thickness, but the thickness of imported cold-rolled plates can reach 4 mm or even 6 mm. Hot-rolled plates of 3 mm to 12 mm are called medium plates, and those of 12 mm or more are called thick plates, which can be thicker than 120 mm, and are called hot-rolled medium-thick plates, while cold-rolled plates are cold-rolled sheets.
