Stainless Steel Angle

Introduction:

Stainless steel angle steel is a long steel bar with two sides perpendicular to each other.

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

25mm equilateral stainless steel angle with 3mm side thickness. It can also be expressed by the model, which is the number of centimeters in width, such as ∠3#. The model does not represent the size of different side thicknesses in the same model, so fill in the side width and side thickness dimensions of stainless steel angle steel on the contract and other documents, so as to avoid expressing it separately by the model. The specification of hot rolled equilateral stainless steel angle steel is 2#-20#.

Stainless steel angle steel can be composed of various stress-bearing components according to different structural needs, and can also be used as a connecting piece between components. Widely used in various building structures and engineering structures, such as house beams, bridges [/url], power transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks and warehouse shelves, etc.

Stainless steel angle steel is a carbon structural steel for construction. It is a section steel with a simple cross section. It is mainly used for metal components and plant frames. It is required to have good weldability, plastic deformation performance and certain mechanical strength in use. The raw material billets for the production of stainless steel angles are low-carbon square billets, and the finished stainless steel angles are delivered in hot-rolled, normalized or hot-rolled state.

Types and specifications:

It is mainly divided into two types: equilateral stainless steel angle steel and unequal equilateral stainless steel angle steel. Among them, unequal equilateral stainless steel angle steel can be divided into unequal equilateral thickness and unequal unequal thickness.

The specifications of stainless steel angle steel are expressed by the dimensions of side length and side thickness. Since 2010, the specifications of domestic stainless steel angle steel have been 2-20, with the number of centimeters of the side as the number. The same stainless steel angle steel often has 2-7 different side thicknesses. Imported stainless steel angles indicate the actual size and thickness of both sides and indicate the relevant standards. Generally, the side length of 12.5cm or more is large stainless steel angle steel, the range of 12.5cm-5cm is medium-sized stainless steel angle steel, and the side length of 5cm or less is small stainless steel angle steel.

The order of import and export stainless steel angle steel is generally based on the specifications required in use, and the steel grade is the corresponding carbon steel grade. In other words, apart from the specification number, stainless steel angle steel has no specific composition and performance series.

The delivery length of stainless steel angle steel is divided into fixed length and double length. The selection range of domestic stainless steel angle steel has four ranges of 3-9m, 4-12m, 4-19m and 6-19m according to different specifications. The length of stainless steel angle steel made in Japan can be selected from 6-15m.

The section height of the unequal stainless steel angle steel is calculated according to the long side width of the unequal stainless steel angle steel.

Appearance quality requirements:

Most of the stainless steel angle steel factory surface is NO.1, customers can customize the matte surface or other surfaces according to requirements, the surface is divided into:No.1/2B/BA/NO. 4/6K/8K/HL(Hairline)/Matting.

The surface quality of stainless steel angle steel is stipulated in the standard, and generally requires that there are no harmful defects in use, such as delamination, scarring, and cracks.

The allowable range of geometric deviation of stainless steel angle steel is also specified in the standard, generally including the degree of curvature, side width, side thickness, vertex angle, theoretical weight, etc., and stipulates that stainless steel angle steel must not have significant torsion.
