Stainless steel Angle bar 316 316L 150*150*5mm Hot rolled Cold rolled and welded
Stainless steel angle steel is a long strip of steel that is perpendicular to each other on both sides. There are equilateral stainless steel angles and unequal stainless steel angles. The sides of the equilateral stainless steel angle are equal in width. The specifications are expressed in millimeters of side width × side width × side thickness. For example, "∠25×25×3" means an equilateral stainless steel angle with a side width of 25 mm and a side thickness of 3 mm. It can also be expressed by model number, the model number is the number of centimeters of the side width, such as ∠2.5#.
The model does not indicate the size of the different side thicknesses in the same model. Therefore, the side width and thickness of the stainless steel angle steel are filled in the contract and other documents, and the model is not to be used alone. The specification of hot-rolled equilateral stainless steel angle steel is 2#-20#.
Type and specification
It is mainly divided into two types: equilateral stainless steel angle steel and unequal side stainless steel angle steel. Among them, the unequal side stainless steel angle steel can be divided into two types: unequal width and unequal thickness.
The specifications for stainless steel angles are indicated by the dimensions of the side length and the side thickness. Since 2010, the specifications of domestic stainless steel angle steels are No. 2-20, and the number of centimeters of the side length is the number. The same stainless steel angle steel often has 2-7 different side thicknesses. The imported stainless steel angle steel indicates the actual size and thickness of the two sides and indicates the relevant standards. Generally, a large stainless steel angle steel with a side length of 12.5 cm or more is a medium-sized stainless steel angle steel between 12.5 cm and 5 cm, and a small stainless steel angle steel with a side length of 5 cm or less.
The order of import and export stainless steel angle steel is generally based on the specifications required in use, and the steel number is the corresponding carbon steel grade. That is, stainless steel angle steel has no specific composition and performance series except for the specification number.
The delivery length of stainless steel angle steel is divided into two types: fixed length and double scale. The range of the fixed length of domestic stainless steel angle steel has four ranges of 3-9m, 4-12m, 4-19m and 6-19m depending on the specification number. The length of stainless steel angle steel produced in Japan ranges from 6 to 15 m.
The section height of the unequal stainless steel angle is calculated as the long side width of the unequal stainless steel angle.
Appearance quality requirements
The surface quality of stainless steel angle steel is specified in the standard. Generally, there must be no harmful defects in use, such as delamination, crusting, cracks, etc.
Unequal angle steel
The allowable range of geometrical deviation of stainless steel angle steel is also specified in the standard, generally including bending, edge width, edge thickness, apex angle, theoretical weight, etc., and specifies that the stainless steel angle steel must not have significant torsion.
