Angle is divided into equal angle and unequal angle types, which can be divided into unequal angle thick and ranging equilateral equilateral two unequal thickness. Angle specifications indicated by side and edge thickness dimensions. At present, the domestic angle specifications for No. 2-20, the number of sides in centimeters long as the number of numbers, the same number of different angles often 2-7 edge thickness. Imported angles indicate the actual size and edge thickness on both sides and indicate the relevant standards. General side length 12.5cm above for large angles, for medium-sized 12.5cm-5cm angle between the side length of 5cm or less for small angles. Angle of import and export orders generally required specifications in use mainly their corresponding carbon steel for structural steel steel. In addition to the standard number is the angle, no specific composition and performance series. Angle chemical composition (1) component indicators: angle of the chemical composition of a general structure of rolled steel series, the main indicators for verification C, Mn, P, S four. Depending on the grade, content differences, and generally in the range of C <0.22%, Mn: 0.30-0.65%, P <0.060%, S <0.060%. (2) Test method: the detection of the chemical composition, the commonly used standard test methods GB223, JISG1211-1215, BS1837, BS Handbook 19, ГОСТ22536 so on. Equilateral angle vector angle of delivery length divided length, foot length times the choice of two types, depending on the size of the domestic angle numbers have 3-9m, 4-12m, 4-19m, 6-19m four range. Japanese production angle of length selection ranges 6-15m. Equilateral angle of unequal angle section height by width to calculate the long side. Refers to the angular cross section and length are not equal on both sides of steel. Is the angle in one. Its side length by 25mm × 16mm ~ 200mm × l25mm. Made by hot rolling mill rolling. General unequal angle specifications: ∠50 * 32 - ∠200 * 125 thickness of 4-18mm unequal angle is widely used in a variety of metal structures, bridges, machinery manufacturing and shipbuilding, various building structures and engineering structures such as beams, bridges, transmission towers, material handling equipment, marine, industrial furnace, reaction tower, container frame and warehouses.
