Angle steel is a long strip of steel with two sides perpendicular to each other, commonly known as angle iron. The following is a detailed description of angle steel:
1, Classification and specifications
Angle steel is mainly divided into two types: equilateral angle steel and unequal angle steel. The length of the two sides of an equilateral angle steel is equal, and its specifications are expressed in millimeters as "edge width x edge width x edge thickness", such as "∠ 30 x 30 x 3", which means an equilateral angle steel with an edge width of 30 millimeters and an edge thickness of 3 millimeters. Unequal angle steel results in unequal lengths of the two sides, making it more flexible and versatile.
The specifications of domestically produced angle steel range from 2 to 20 centimeters, with the length of the side measured in centimeters as the number. The same angle steel often has 2 to 7 different edge thicknesses. Imported angle steel shall indicate the actual dimensions and edge thickness on both sides, as well as relevant standards.
2, Production method
Hot rolling: The most common method of producing angle steel, suitable for producing standard sizes and large quantities of angle steel.
Cold drawing: suitable for producing angle steel with finer dimensions and stricter tolerances, providing higher strength and better surface quality.
Forging: mainly used for producing large-sized or specially required angle steel, which can obtain better grain structure and improve its overall performance.
3, Features and Applications
Angle steel has good weldability, plastic deformation performance, and certain mechanical strength. It is a carbon structural steel used in construction and belongs to the category of simple section steel.
Angle steel is widely used in various building and engineering structures, such as beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks, and warehouses.
Angle steel can also be used to form various load-bearing components according to different structural needs, and can also be used as connectors between components.
4, Other information
The main verification indicators for the chemical composition of angle steel are C, Mn, P, and S, with varying contents.
The delivery length of angle steel is divided into two types: fixed length and double length. The selection range of fixed length for domestic angle steel varies depending on the specification number.
The weight calculation formula for angle steel is: weight per meter=0.00785 × (edge width+edge width - edge thickness) × edge thickness, but this algorithm can only roughly calculate the weight of angle steel. The actual weight should be based on the hardware manual.
In summary, angle steel plays an important role in various fields due to its unique shape and excellent mechanical properties.
