Stainless Steel Angle

Stainless Steel Angle

Time:2022-04-07 Source:Wuxi Jianuo Special Steel Co.

Stainless steel angle is a long strip of steel with two sides perpendicular to each other in an angle shape.

Product Description Editor

Its specifications are expressed in mm of side width × side width × side thickness. Such as “∠25×25×3”, that is, the side width of

25 mm, the side thickness of 3 mm equilateral stainless steel angle. Also available model number, the model number is the number of centimeters of side width, such as ∠ 3 #. Model does not indicate the same model in different side thickness of the size, and therefore in the contract and other documents will be the side of the stainless steel angle width, side thickness size to fill out the complete, avoid using the model alone. Hot rolled equilateral stainless steel angle specifications for 2#-20#.

Stainless steel angle can be composed of various different force members according to the different needs of the structure, but also can be used as the connection between the members. Widely used in a variety of building structures and engineering structures, such as beams, bridges[/url], power transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks and warehouse shelves.

Stainless steel angle is a carbon structural steel for construction, is a simple section of the section steel, mainly used for metal components and plant framework, etc.. In use requires a good weldability, plastic deformation properties and a certain mechanical strength. Production of stainless steel angle raw material billet for low carbon square steel billet, finished stainless steel angle for hot roll forming, normalized or hot rolled state delivery.

Types and specifications editor

Mainly divided into equilateral stainless steel angle and unequal stainless steel angle two categories, which can be divided into unequal stainless steel angle and unequal thickness of unequal sides and unequal thickness of two.

The specifications of stainless steel angles are indicated by the size of the side length and side thickness. 2010 since the domestic stainless steel angle specifications for 2-20, to the number of centimeters of the side length for the number, the same number of stainless steel angle often has 2-7 different side thickness. Imported stainless steel angle marked with the actual size of the two sides and the side thickness and indicate the relevant standards. General side length of 12.5cm or more for large stainless steel angle, 12.5cm-5cm between the medium-sized stainless steel angle, the side length of 5cm or less for small stainless steel angle.

The delivery length of stainless steel angle is divided into two types of fixed length, times the length of domestic stainless steel angle selection range according to the specification number of 3-9m, 4-12m, 4-19m, 6-19m four ranges. Japan-made stainless steel angle length selection range of 6-15m.

The cross-sectional height of unequal stainless steel angles is calculated by the width of the long side of unequal stainless steel angles.

Appearance quality requirements edit

The surface quality of the stainless steel angle is specified in the standard, and generally requires that there shall be no defects harmful to use, such as delamination, scars, cracks, etc.

Unequal angle steel

Stainless steel angle geometry deviation of the allowable range in the standard is also specified, generally including curvature, side width, side thickness, top angle, theoretical weight and other items, and provides that stainless steel angle shall not have a significant twist.

Chemical composition test editor

(1) composition indicators: the chemical composition of stainless steel angle is a general structural rolling steel series, the main test indicators for C, Mn, P, S four. Depending on the grade, the content varies, the approximate range of C < 0.22%, Mn: 0.30-0.65%, P < 0.060%, S < 0.060%.

(2) Test methods: When testing the above chemical composition, the commonly used standard test methods are GB223, JISG1211-1215, BS1837, BS Manual 19, ГОСТ22536, etc.

Specification standards editor

Stainless steel angle should be delivered in bundles, the bundle of the road, the same bundle length, etc. should be in line with the provisions. Stainless steel angles are generally delivered bare, transportation and storage are required to pay attention to protection.
