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 steel 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 rule. The range of 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 range of Japanese stainless steel angle steel is 6-15m. The section height of the unequal stainless steel angle is calculated as the long side width of the unequal stainless steel angle. Import and export situation editing China's imported and exported stainless steel angle steels have a certain volume, mainly imported from Japan and Western Europe. The export areas are mainly Hong Kong, Macao, Southeast Asia, Latin America and Arab countries. The export production enterprises are mainly steel plants (rolling mills) in Jiangsu, Liaoning, Hebei, Beijing, Shanghai, Tianjin and other provinces and cities. The imported stainless steel angle steels are mostly large and small stainless steel angle steels and special shape stainless steel angle steels. Most of the exported varieties are medium-sized stainless steel angle steels such as No.6 and No.7. Appearance quality requirements editor 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 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. 304 stainless steel channel steel is a stainless steel channel made of 304 stainless steel. Stainless steel channel steel is a long strip of steel with a cross-sectional shape of a groove. Same as I-beam, stainless steel channel steel is also divided into ordinary channel steel and light channel steel. The model and specification are also expressed in millimeters of waist height (h) × leg width (b) × waist thickness (d). Such as 120 × 53 × 5 channel steel. It can also be expressed in centimeters of waist height, as the channel steel is called 12# channel steel, and its specification range is 5-40#. 304 stainless steel channel steel is the most commonly used stainless steel channel steel, commonly used in construction, steel frame construction, vehicle manufacturing and other industrial structures.
