Open plate

EN 10025-2 is European standard, EN 10025-2 Carbon Steel is a steel alloy where carbon is the main alloying element.

Carbon steel can be grouped into 3 categories: Low Carbon Steel (also known as Mild Steel), Medium Carbon Steel and High Carbon Steel.

Open plate It is a steel plate with a certain thickness and width rolled according to the user\'s requirements. The original plate is rolled into the size required by the national standard when it leaves the factory. Generally, the original plate has strict size, good performance and high price. The flat panel is relatively cheap, and the size is slightly different.

  brief introduction
The open plate is a colloquial name. In gb709, which is being revised, the open plate and the original plate should be referred to as: shear steel plate and single rolled steel plate respectively. The steel plate is rolled when it comes out of the steel plant. The flat plate after being leveled by the machine is called \"open plate\", just like the whole roll of toilet paper. The internal stress level of the open plate is high, so the dimensional stability is poor. The internal stress distribution varies with the process parameters during the leveling operation, and the bearing capacity varies in different directions of the vertical length. Moreover, this bearing capacity is difficult to be measured by the general strength index. Therefore, the open plate will have great welding deformation during welding, which is difficult to adjust. Therefore, parts with high requirements for appearance quality cannot use split plates.

The open plate is a steel plate with a certain thickness and width rolled according to the user\'s requirements. The original plate is rolled into the size required by the national standard when it leaves the factory. Generally, the original plate has strict size, good performance and high price. The flat panel is relatively cheap, and the size is slightly different. The split plate is 1.5-20mm thick and made of Q235 and q355. It is mainly used for non pressure vessels and storage tanks.

 Advantages
  I The price is cheap and the length can be decided freely;
  II It is convenient to transport without considering the size of steel plate;
  III It is convenient to cut the steel plate according to the actual needs;
  IV It can effectively save materials.
For example, a tank needs 6800 × one thousand and five hundred × There are 20 steel plates of 6. The market steel plates are generally 6000, 8000 and 9000 in length. If the market steel plates are used, there will be small pieces of surplus materials. With the flat plate, 6900 steel plate can be directly used to save materials, which is also the greatest advantage. Especially for stainless steel materials, the effect of saving materials and reducing costs is very obvious.
