Alloy angle steel
Short Description:
Angle steel can form various stress components according to different structural needs, and can also be used as connectors between components. Widely used
It is applicable to various building structures and engineering structures, such as house beams, bridges, transmission towers, hoisting and transportation machinery, ships, industrial furnaces, reaction towers, container racks, cable trench supports, power piping, bus support installation, warehouse shelves, etc.
Angle steel is a carbon structural steel for construction. It is a section steel with simple section. It is mainly used for metal components and plant frame. In use, it is required to have good weldability, plastic deformation performance and certain mechanical strength. The raw material billet for angle steel production is low-carbon square billet, and the finished angle steel is delivered in hot rolling forming, normalizing or hot rolling state.
Type and specification
It is mainly divided into equilateral angle steel and unequal angle steel. Unequal angle steel can be divided into unequal edge equal thickness and unequal edge unequal thickness.
The specification of angle steel is expressed by the dimension of side length and side thickness. At present, the specification of domestic angle steel is 2-20, with the number of centimeters of side length as the number. The same angle steel often has 2-7 different side thicknesses. The actual size and thickness of both sides of the imported angle steel shall be indicated, and relevant standards shall be indicated. Generally, the large angle steel with a side length of more than 12.5cm, the medium angle steel with a side length of 12.5cm-5cm, and the small angle steel with a side length of less than 5cm.
The order of import and export angle steel is generally based on the specifications required in use, and its steel grade is the corresponding carbon steel grade. It is also an angle steel. In addition to the specification number, there is no specific composition and performance series.

The delivery length of angle steel is divided into fixed length and double length. The fixed length selection range of domestic angle steel is 3-9m, 4-12m, 4-19m and 6-19m according to the specification number. The length selection range of angle steel made in Japan is 6-15m.
The section height of unequal angle steel is calculated according to the length and width of unequal angle steel. It refers to steel with angular section and unequal length on both sides. It is one of the angle steel. Its side length is 25mm × 16mm~200mm × l25mm。 It is rolled by hot rolling mill. The specification of general unequal angle steel is: ∟ 50 * 32 — ∟ 200 * 125, and the thickness is 4-18mm
Unequal angle steel is widely used in various metal structures, bridges, machinery manufacturing and shipbuilding, various building structures and engineering structures, such as house beams, bridges, transmission towers, hoisting and transportation machinery, ships, industrial furnaces, reaction towers, container racks and warehouses
