Detail
Stainless steel flat bars are rectangular steels with slightly pure edges. Stainless steel flat steel can be semi-finished steel. There are cold-drawn polished stainless steel flat steel and hot-rolled acid white sandblasted stainless steel flat steel.
Stainless steel flat steel can be composed of various stress-bearing components according to the different needs of the structure, and can also be used as a connection between components. It is widely used in various building structures and engineering structures, such as beams, bridges, transmission towers, lifting and transporting machinery, ships, industrial furnaces, reaction towers, container racks and warehouse racks.
Stainless steel flat steel is used as bridges, house frames, fences, power transmission ships, vehicles, etc. in construction projects. 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 hot-rolled, cold-rolled or hot-rolled state. During the transaction, the side width and side thickness of the stainless steel flat steel should be fully filled in the contract and other documents, as well as other main process matters, such as annealing, solid solution, etc.
Types and Specifications
It is mainly divided into two types: equilateral and unequal. Among them, equilateral can be divided into square steel. The specifications are expressed by the dimensions of side length and side thickness. The current domestic specifications are 3mm*20m-150mm.
Import and export orders are generally based on the specifications required in use, and their steel grades are the corresponding carbon steel grades. That is, other than the specification number, there is no specific composition and performance series.
The delivery length of stainless steel flat steel is divided into fixed length and double length. The selection range of domestic fixed length is 3-9m and 4-12m according to the different specifications. The length selection range of Japan is 6-15m.
import and export
my country's imports and exports have certain batches, mainly from Japan and Western Europe. The main export destinations are Hong Kong and Macau, Southeast Asia, Latin America and Arab countries. The export production enterprises are mainly steel mills (rolling mills) in Jiangsu, Liaoning, Hebei, Beijing, Shanghai, Tianjin and other provinces and cities.
Appearance Quality
The surface quality of stainless steel flat steel is specified in the standard, and it is generally required that there should be no harmful defects in use, such as delamination, scarring, cracks, etc.
The allowable range of geometric deviation is also specified in the standard, which generally includes items such as curvature, side width, side thickness, vertex angle, theoretical weight, etc., and a significant twist is specified.
