Angle Steel 50x50 Steel 45 Degree Angle Iron

Angle Steel 50x50 Steel 45 Degree Angle Iron   /  ASTM A36 equal angle steel    

 commonly known as angle iron , perpendicular to each other on both sides of a triangle strip steel. Angle has equilateral angles and unequal angle of the points. Equilateral angle of the two sides equal width. Its specifications represented in side edge width × width × edge thickness of a few millimeters. Such as "∠30 × 30 × 3", it means that edge width of 30 mm, edge thickness of 3 mm equilateral angle. Models can also be said that the model is a few centimeters wide edge, as ∠3 #. Models do not represent different sides of the same thickness dimension models, contracts and other documents will thus angle of edge width, edge thickness dimension completely filled, avoid models alone represent. Hot-rolled equilateral angle specifications for the 2 # -20 #. Angle structure according to the different needs of the composition of the various components of the force, but also for connections between the components. It is widely used in various building structures and engineering structures, such as beams, bridges, transmission towers, lifting the transport machinery, shipbuilding, industrial furnace, reaction tower, container racks and warehouse shelves.

 1  Angle Profile

Angle structure according to the different needs of the composition of the various components of the force, but also for connections between the components. Widely used in various building structures and engineering structures, such as beams, bridges, transmission towers, lifting the transport machinery, shipbuilding, industrial furnace, reaction tower, container racks, cable channel bracket, power piping, bus bracket, as well as warehouse shelves.

Angle genus constructed of carbon steel, section steel simple steel, mainly used in the framework of metal components and factories and so on. In use, it requires a good weldability, and the plastic deformation properties of a certain mechanical strength. Angle steel billet production of raw materials for the low-carbon square billet, hot-rolled finished forming angle, normalizing or hot-rolled state delivery.

 2  Category Specification

Divided into equal angle and unequal angle into two categories, which can be divided into thick equilateral angle and unequal scalene equilateral two unequal thickness.

Angle specifications indicated by side and edge thickness dimensions. Current domestic angle specifications for the 2-20, the number of edges in centimeters long number is the number, the same number of different angles often 2-7 edge thickness. Imported angle indicating 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 the use of specifications based, its steel carbon structural steel for the corresponding steel number. In addition to the standard number is the angle, no specific composition and performance series. Angle of delivery length divided length, times two feet, made of cut-angle range of options depending on the number of specifications have 3-9m, 4-12m, 4-19m, 6-19m four ranges. Japanese production angle of length selection range of 6-15m.

Equilateral angle steel 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 one angle. Its side by a 25mm × 16mm ~ 200mm × l25mm. Formed by the hot rolling mill rolling. Generally ranging from side angle specifications: ∠50 * 32 - ∠200 * 125 thickness of 4-18mm

Equilateral angle steel is widely used in all kinds of metal structures, bridges, machinery manufacturing and shipbuilding, various building structures and engineering structures, such as beams, bridges, transmission towers, lifting the transport machinery, shipbuilding, industrial furnace, reaction tower, and other container racks and warehouse

 3  Appearance Quality

Angle of the surface quality are specified in the standard, general requirements may not exist on the use of harmful defects, such as delamination, scarring, cracks.

Angle geometry deviation allowable range specified in the standard are also generally include bending, edge width, edge thickness, angle, theoretical weight of other items, and provides a significant angle can not be reversed.

 4  Chemical composition

(1) Component indicators: the chemical composition of a general angle structural rolled steel series, the main verification indicators C, Mn, P, S four. According to different grades, content differences, and generally in the range of C <0.22%, Mn: 0.30-0.65%, P <0.060%, S <0.060%.

(2) Inspection methods: the detection of the chemical composition, the commonly used standard test method GB223, JISG1211-1215, BS1837, BS Handbook 19 like.*

(3)  Our products can be customized according to customer requirements

 5  Specifications standard

GB / T2101-89 (steel inspection, packaging, marking and quality certification of general provisions); GB9787-88 / GB9788-88 (hot-rolled edge / unequal angle size, shape, weight and tolerance); JISG3192- 94 (hot-rolled steel shape, size, weight and Tolerance); DIN17100-80 (ordinary structural steel quality standards).

According to the standards, the angle should be a bundle of delivery, the strapping passes, with the bundle length should be specified. Angle is generally within the bare delivery, transport and storage of all need to pay attention to moisture.

 6  Mechanical behavior

(1) Test method:

tensile test method. Commonly used standard test method GB / T228-87, JISZ2201, JISZ2241, ASTMA370, BS18, DIN50145, etc;

bend test methods. Commonly used standard test method GB / T232-88, JISZ2204, JISZ2248, ASTME290, DIN50111 and other.

(2) Performance indicators: assessment of the performance test angle mainly for tensile test and bending test. Indicators include yield point, tensile strength, elongation and bending qualified peers.
