    Stainless steel angle steel

    Stainless steel angle steel is a long steel strip whose sides are perpendicular to each other. There are equilateral stainless steel angle steel and unequal stainless steel angle steel. Equilateral stainless steel angle steel has the same width on both sides. Its specifications are expressed in millimetres of edge width * edge width * edge thickness. For example, "25 *25 *3" means equal-sided stainless steel angle with a width of 25 mm and a thickness of 3 mm. It can also be expressed as the number of centimeters of the side width, such as 2.5#. The model does not represent the dimensions of different edge thicknesses in the same model. Therefore, the dimension of the edge and edge thicknesses of stainless steel angle steels should be filled in completely on the contract documents, avoiding using the model alone. The specification of hot-rolled equilateral stainless steel angle steel is 2-20.
    Summary
    Its specifications are expressed in millimetres of edge width * edge width * edge thickness. For example, "25*25*3", that means the width of the edge is
    Equilateral stainless steel angle with 25 mm edge thickness and 3 mm edge thickness. It can also be expressed as the number of centimeters of the edge width, such as 3#. The model does not represent the dimensions of different edge thicknesses in the same model. Therefore, the dimension of the edge and edge thicknesses of stainless steel angle steels should be filled in completely on the contract documents, avoiding using the model alone. The specification of hot-rolled equilateral stainless steel angle steel is 2-20.
    Stainless steel angle steel can be used to form various stress components according to the different needs of the structure, and can also be used as a connection between components. It is widely used in various building structures and engineering structures, such as beams, bridges [/url], transmission towers, lifting machinery, ships, industrial furnaces, reaction towers, container shelves and warehouse shelves.
    Stainless steel angle steel is a carbon structural steel for construction. It is a simple section steel. It is mainly used for metal components and the frame of workshop. Good weldability, plastic deformation and mechanical strength are required in use. The raw billet for producing stainless steel angle steel is low carbon square billet, and the finished stainless steel angle steel is delivered in hot rolling, normalizing or hot rolling state.
    Categories and specifications
    It can be divided into two kinds: equal-edge stainless steel angle steel and unequal-edge stainless steel angle steel. The unequal-edge stainless steel angle steel can be divided into unequal-edge equal-thickness and unequal-edge unequal-thickness.
    The specification of stainless steel angle steel is expressed by the size of side length and thickness. Since 2010, the specification of domestic stainless steel angle steel is No. 2-20, with the number of centimeters of edge length. The same stainless steel angle steel often has 2-7 different edge thicknesses. Imported stainless steel angle steel indicates the actual size and thickness of both sides and the relevant standards. Generally, large stainless steel angle steel is more than 12.5 cm in edge length, medium stainless steel angle steel is between 12.5 cm and 5 cm in edge length, and small stainless steel angle steel is below 5 cm in edge length.
    The import and export orders of stainless steel angle steel are generally based on the specifications required in use, and its steel number is the corresponding carbon-bonded steel number. That is to say, stainless steel angle steel has no specific composition and performance series except specification number.
    The delivery length of stainless steel angle steel can be divided into two types: fixed length and double length. The selection range of domestic stainless steel angle steel is 3-9m, 4-12m, 4-19m and 6-19m according to different specifications. The length of Japanese stainless steel angle steel ranges from 6 to 15m.
    The section height of unequal stainless steel angle steel is calculated by the long side width of unequal stainless steel angle steel.
    Chemical Composition Testing
    (1) Composition index: The chemical composition of stainless steel angle steel belongs to the rolling steel series for general structure. The main inspection indexes are C, Mn, P and S. According to the different grades, the contents varied, ranging from C < 0.22%, Mn: 0.30-0.65%, P < 0.060%, S < 0.060%.
    (2) Inspection methods: When detecting the above chemical constituents, the commonly used standard methods are GB223, JISG1211-1215, BS1837, BS Manual 19, 
    Specification standard
    GB9787-88/GB9788-88 (Hot Rolled Equilateral/Unequal Side Stainless Steel Angle Size, Shape, Weight and Allowable Deviation); JISG3192-94 (Hot Rolled Section Steel Shape, Size, Weight and Allowable Deviation); DIN17100-80 (General Structure); Steel Quality Standard; 535-88 (Technical Conditions for Common Carbon Section Steel).
    According to the above standards, stainless steel angle steel should be delivered in bundles, the bundling passes and the length of the same bundle should meet the requirements. Stainless steel angle steel generally belongs to bare delivery, transportation and storage should pay attention to moisture-proof.
    Inspection of mechanical properties
    (1) Test methods:
    (1) Tensile test method. Commonly used standard inspection methods are GB/T 2228-87, JISZ2201, JISZ2241, ASTM A370, 1497, BS18, DIN50145, etc.; 2. Bending test methods. The commonly used standard test methods are GB/T 232-88, JISZ2204, JISZ2248, ASTME290, 14019, DIN50111, etc.
    (2) Performance indicators: Tensile test and bending test are the main items to test the properties of stainless steel angle steel. Indicators include yield point, tensile strength, elongation and bending qualification.
