Stainless steel angle steel is a long strip of steel with two sides perpendicular to each other and forming an angle. There are equal sided stainless steel angles and unequal sided stainless steel angles. The two sides of an equilateral stainless steel angle steel have equal widths. Its specifications are based on edge width × Edge width × The thickness of the edge is expressed in millimeters. As shown in "∠ 25 × twenty-five × 3 "refers to an equilateral stainless steel angle steel with an edge width of 25mm and an edge thickness of 3mm. It can also be represented by a model, which is the number of centimeters of edge width, such as ∠ 2.5 #. The model does not represent dimensions with different edge thicknesses within the same model. Therefore, the edge width and thickness dimensions of stainless steel angle steel should be fully filled in the contract and other documents to avoid using the model alone. The specifications of hot-rolled equilateral stainless steel angle steel are 2 # -20 #.
The acceptance criteria of angle steel and channel steel include: the main inspection items for evaluating the performance of angle steel and channel steel are Tensile testing and bending test. The indicators include yield point, tensile strength, elongation, and bending qualification. The specific standards are as follows:
1. Tensile testing method. The commonly used standard inspection methods include GB/T228-87, JISZ2201, JISZ2241, ASTMA370 ГОСТ 1497, BS18, DIN50145, etc;
2. Bending test method. The commonly used standard inspection methods include GB/T232-88, JISZ2204, JISZ2248, ASTME290 ГОСТ 14019, DIN50111, etc.
Angle iron, commonly known as angle iron, is a long strip of steel with two sides perpendicular to each other and forming an angle shape. There are two types of angles: equal angle steel and unequal angle steel. The two sides of an equilateral angle steel have equal widths. Its specifications are based on edge width × Edge width × The thickness of the edge is expressed in millimeters. Channel steel is a long strip of steel with a groove shaped cross-section. A steel section with a groove shape.
