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.

Which is better ss304 or ss316?

Since Type 316 stainless steel alloy contains molybdenum bearing it has a greater resistance to chemical attack than 304. Type 316 is durable, easy-to-fabricate, clean, weld and finish. It is considerably more resistant to solutions of sulfuric acid, chlorides, bromides, iodides and fatty acids at high temperature.
What is good quality stainless steel?
304 stainless steel is the most common form of stainless steel used around the world due to excellent corrosion resistance and value. 304 can withstand corrosion from most oxidizing acids. That durability makes 304 easy to sanitize, and therefore ideal for kitchen and food applications.

What is the difference between 304, 304H and 304L?

In fact, the content of chromium and nickel is 304 stainless steel, and the composition contains 18% chromium (Cr) and 8% nickel (Ni), but the main difference lies in the carbon content.

304L is an ultra-low carbon stainless steel. The carbon content is reduced to less than 0.03%, which can avoid intergranular corrosion. In theory, the effect of stress corrosion resistance is stronger than that of 304, but the effect is not obvious in practical applications. The purpose of reducing carbon and adding titanium is the same, but the smelting cost of titanium-added 321 is higher, the molten steel is thick, and the price is more expensive.

The H in 304H refers to high temperature. High carbon content is the guarantee of high temperature strength. GB150 requires that when austenitic steel is used above 525 degrees, the carbon content should not be less than 0.04%. Carbide is the strengthening phase, especially the high temperature strength. Better than pure austenite.

Among the three, the highest carbon content is 304H, the lowest carbon content is 304L, and the carbon content of 304 stainless steel is between the two. The higher the carbon content, the worse the corrosion resistance of stainless steel and the easier it is to rust. The difference in carbon content also causes the price to be different, or the requirements for different uses are also different.

Why is stainless steel so expensive?

Stainless steel is more expensive to produce because of the addition of the variety of alloying elements, such as iron, chromium, nickel, manganese and copper. … The chromium attaches itself to oxygen more readily than iron and thus creates a chromium oxide layer which protects the metal from degradation.
What is the safest stainless steel?
Stainless steel cookware is generally recognized as a safe material for cookware. Any good quality stainless steel, be it 304 or 316 stainless steel, is a better choice than most of the other available materials. For example, coated aluminum pans lose their non-stick over time.
