Introduction of 310S stainless steel angle bar

Written by

310S stainless steel angle bar is widely used as engineering structures of various buildings, such as beams, bridges, towers, hoisting and conveying machinery, ships, industrial furnace, reaction tower, container or even warehouse shelves. From the angle of the name can be seen made of 310S stainless steel, 0Cr25Ni20 stainless steel grades for GB, this is also called the 2520 stainless steel is a kind of austenitic chromium nickel stainless steel, has excellent oxidation resistance and corrosion resistance, and also because of the high proportion of chromium and nickel content, 310S stainless steel has excellent creep strength and, good high temperature performance, can continuously work under high temperature.

Due to the high nickel and high chromium content in 310S stainless steel, so its resistance to oxidation, corrosion resistance, acid and alkali resistance, high temperature performance is very good, so for 310S stainless steel as raw material, high temperature resistant steel can be made into the electrothermal furnace tube and other products, increasing the carbon content in austenitic stainless steel, can enhance its solid solution strengthening effect and increase strength, chemical composition characteristics of austenitic stainless steel is chrome, nickel based addition of molybdenum and tungsten, niobium and titanium elements, also because of its organization is face centered cubic structure, so the strength and good creep strength at high temperature.

310 stainless steel is now widely used, including petroleum, electronics, chemical, pharmaceutical, textile, food, machinery, construction, nuclear power, aerospace, military and other industries.

So what is stainless steel angle bar? An angle bar is a long strip of steel with angles perpendicular to each other. There are two kinds of shape, namely equilateral stainless steel angle bar and scalene stainless steel angle. The two side widths of equilateral stainless steel angles are basically equal, and their specifications are expressed by the width of the edge, the width of the side, the width of the side and the thickness of the edge. In addition, scalene stainless steel angles can be divided into two kinds: unequal thickness, unequal thickness and unequal thickness.

The specifications of stainless steel angles can be expressed by the length of the side and the thickness of the edges. Domestic stainless steel angle specifications for 2 – 20 cm, to length number number, the same number of stainless steel angle bar is often 2 – 7 different edge thickness. Import stainless steel angles mark the actual size and edge thickness of both sides, and indicate the relevant standards. The stainless steel angle is usually larger than 12.5cm, and the angle between 12.5cm and 5cm is medium stainless steel angle. The stainless steel angle is smaller than 5cm.

The import and export of stainless steel angle bar in China has a certain quantity, generally imported from Japan and Western Europe, and exports mainly to Hong Kong and Macao, Southeast Asia, Latin America and Arabia countries. The export enterprises are mainly steel mills (rolling mills) in Jiangsu, Liaoning, Hebei, Beijing, Shanghai, Tianjin and other provinces and municipalities.

Imported stainless steel angle bar varieties are large, small stainless steel angle bar and special shape of stainless steel angle bar, export varieties are medium stainless steel angle, such as 6, 7, etc..

The surface quality of stainless steel angle bar has certain standard stipulation. It is usually required that there is no disadvantage which is unfavorable to application, such as delamination, scab, crack, etc.. The allowable range of the geometric deviation of stainless steel angle bar is also stipulated by the standard, usually including bending, edge width, edge thickness, vertex angle, theoretical weight and so on, and the stainless steel angle shall not have significant torsion.
