Angle steel is mainly divided into equal-edge Angle steel and unequal edge Angle steel, which can be divided into unequal edge thickness and unequal edge thickness two kinds.The specification of Angle steel is indicated by side length and side thickness.At present domestic Angle steel specification is 2, 20, with the centimeter number of side length is number, same Angle steel often has 2, 7 kinds of different edge thickness.The actual dimensions and thickness of both sides of imported Angle steel are indicated and relevant standards are indicated.Generally, large Angle steel with side length more than 12.5cm, medium Angle steel with side length between 12.5cm and 5cm, and small Angle steel with side length less than 5cm.Import and export Angle steel orders generally to use the required specifications, the steel number of the corresponding carbon steel.Angle steel is also in addition to the specification number, no specific composition and performance series.The delivery length of Angle steel is divided into two types: fixed size and double size. The selection range of fixed size of domestic Angle steel is 3 -- 9m, 4 -- 12m, 4 -- 19m and 6 -- 19m according to the different specifications.The length range of Angle steel produced in Japan is 6-15m.
The section height of unequal Angle steel is calculated by the long side width of unequal Angle steel.Steel with angular sections and unequal lengths on both sides.It's a type of Angle steel.The side length is 25mm×16mm ~ 200mm×l25mm.It is rolled by a hot rolling mill.General specifications of unequal Angle steel: Angle 50*32- Angle 200*125 thickness of 4-18mmNon-equal-edge Angle steel is widely used in various metal structures, Bridges, machinery manufacturing and shipbuilding industry, various building structures and engineering structures, such as beams, Bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container frames and warehousesWhat is the chemical composition of Angle steel?(1) composition index: the chemical composition of Angle steel belongs to the rolling steel series for general structure, and the main verification indexes are C, Mn, P and S.According to different brands, the content varies, generally ranging from C<0.22%, Mn: 0.30-0.65%, P<0.060%, S<0.060%.(2) inspection method: to test the chemical composition of the Angle, the Angle of the specifications of the commonly used standard inspection method the GB223, JISG1211-1215, BS1837, 19 of the manual, BS Г О С Т 22536 etc.The above is the Angle steel chemical composition and other related introduction, if you have other questions can consult our online customer service, we will wholeheartedly for your service!
