The chemical composition of angle steel and the scope of application of angle steel. For many people, the use of angle steel is still relatively familiar, but most people may not be able to say the chemical composition. Today we will learn about the chemical composition of angle steel and the scope of application of angle steel.

Angle steel, commonly known as angle iron, is a long strip of steel with two sides perpendicular to each other. Its chemical composition and testing methods are described as follows:
(1) Composition index: The chemical composition of angle steel belongs to the series of rolled steel for general structure, and the main verification indexes are C, Mn, P and S. According to different brands, the content is different, the approximate range is C<0.22%, Mn: 0.30-0.65%, P<0.060%, S<0.060%.
(2) Inspection method: When testing the above chemical composition of angle steel, the commonly used standard inspection methods to understand the chemical composition of angle steel are GB223, JISG1211-1215, BS1837, BS Manual 19, "OCT22536, etc.

Angle steel facilitates the construction of various large-scale buildings, so what are the applicable scope of angle steel?
1. Widely used in light industry
2. Suitable for construction industries such as railways, highway protection, street light poles, etc.
3. For marine components
4. Suitable for power towers, communication towers and other projects
