Angle steel, affectionately referred to as angle iron, stands as a vital component in the steel industry, characterized by its long strip design with two sides meeting perpendicularly. This provides an in-depth exploration of its diverse qualities and applications:
1, Classification and Specifications
Angle steel is primarily categorized into two distinct types: equilateral angle steel and unequal angle steel. Equilateral angle steel boasts equal side lengths, denoted in millimeters as 'edge width x edge width x edge thickness'. For instance, '∠ 30 x 30 x 3' signifies an equilateral angle steel with a 30-millimeter edge width and a 3-millimeter thickness. Meanwhile, unequal angle steel, with its differing side lengths, offers enhanced adaptability and versatility for various applications.
Domestic angle steel is available in specifications ranging from 2 to 20 centimeters, with side lengths represented by these numbers. A single angle steel type may present between 2 and 7 distinct edge thickness options. Imported varieties must clearly delineate actual dimensions and thicknesses on each side, adhering to pertinent standards.
2, Production Method
Hot Rolling: This predominant production method is ideally suited for crafting standard-sized and large-quantity angle steel.
Cold Drawing: Tailored for angle steel requiring finer dimensions and stricter tolerances, this method enhances strength and surface quality.
Forging: Employed for creating large-scale or specially specified angle steel, this method improves grain structure and bolsters overall performance.
3, Features and Applications
Angle steel exemplifies commendable weldability, plasticity in deformation, and sufficient mechanical strength. Classified as carbon structural steel, it serves a pivotal role in construction as a simple section steel.
With its versatility, angle steel finds widespread use across myriad building and engineering frameworks, including beams, bridges, transmission towers, hoisting and transport machinery, ships, industrial furnaces, reaction towers, container racks, and storage facilities.
Its adaptability allows angle steel to form various load-bearing components tailored to structural demands and to function as connectors between different parts.
4, Other Information
The chemical composition of angle steel is critically assessed based on key indicators like C, Mn, P, and S, each having different concentrations.
Angle steel delivery lengths are categorized as either fixed or double length, with domestic fixed lengths varying according to specification numbers.
The approximate weight of angle steel is determined using the formula: weight per meter = 0.00785 × (edge width + edge width - edge thickness) × edge thickness. However, actual weight should be referenced from the hardware manual for precision.
In conclusion, angle steel is indispensable across various sectors, celebrated for its distinct shape and superior mechanical properties, making it integral to structural integrity and architectural innovation.
