Stainless steel flat steel application
Stainless steel flat steel can be used to form different stress components according to different structural requirements, and can also be used as the connection between components. It is widely used in various building structures and engineering structures, such as beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks and warehouse shelves.
Stainless steel flat steel is used as bridge, house frame, fence, transmission ship, vehicle and so on. The raw material billet for the production of stainless steel flat steel is low carbon square billet, and the finished stainless steel flat steel is delivered in the state of hot rolling forming, cold rolling or hot rolling. During the transaction, the side width and thickness of the stainless steel flat steel shall be fully filled in the contract and other documents, as well as the main technical matters, such as annealing, solid solution, etc. It is mainly divided into equilateral and non equilateral types, and equilateral can be divided into square steel specifications, which are expressed by the size of side length and edge thickness. At present, the domestic specifications are 3 mm * 20 M-150 mm.
Import and export orders are generally based on the specifications required in use, and the steel grade is the corresponding carbon steel grade. In other words, there is no specific composition and performance series except for the specification number.
The delivery length of stainless steel flat steel can be divided into fixed length and double length. The selection range of domestic fixed length is 3-9m and 4-12m according to the specification number. The length selection range of Japanese made is 6-15m. The surface quality of stainless steel flat steel is stipulated in the standard. Generally, harmful defects such as delamination, scab and crack shall not exist.
The allowable range of geometric shape deviation is also specified in the standard, generally including bending degree, side width, edge thickness, top angle, theoretical weight and other items, and it is required to have significant torsion
