Angle iron, commonly known as corner iron, is both sides vertical angles of long steel.

commonly known as: corner iron shape: both sides vertical angles of long steel

Classification

equal angle steel and Unequal Angle Steel

Material carbon structure steel raw material billet low carbon square steel billet.

Angle steel can form a variety of different stressed components according to different structure needs, or as connections between components. It is widely used in a variety of building structures and engineering structures such as building beams, bridges, transmission towers, lifting transport machinery, ships, industrial furnaces, reaction towers, container racks, cable trench supports, power piping, bus support installation, and warehouse shelves.

Angle steel is a carbon structural steel for construction, is a simple section of type steel steel, mainly used for metal components and plant frame. Good weldability, plastic deformation performance and certain mechanical strength are required in use. The raw material billet of producing angle steel is low-carbon square billet, and the finished angle steel is hot rolled forming, hot or hot rolled state delivery.

Chemical composition

(1) Composition index: the chemical composition of angle steel is a rolled steel series for general structure, and the main verification indexes are C, Mn, P, S four. Depending on the label, content range C <0.22%, Mn:0.30—0.65%, P <0.060% and S <0.060%.

Mechanical properties

(1) Inspection method:

① tensile test method. Common-used standard inspection methods are GB/T228-87, JISZ2201, JISZ2241, ASTMA370, ГОСТ1497, BS18, DIN50145;

② Bending Test Method. Common-used standard test methods are GB/T232-88, JISZ2204, JISZ2248, ASTME290, ГОСТ14019, DIN50111, etc.

(2) Performance indicators: the inspection items of assessing angle steel performance are mainly tensile test and bending test. They include yield point, tensile strength, elongation and bending qualification.

=0.00785 * (+ wide-thick) * Side thickness

Example 50 * 5 angle steel: (50+50-5)*5*0.00785=3.73
