We have introduced more than 50 sets of advanced S690Q chemical composition production equipment, auxiliary equipment and testing equipment at home and abroad, more than 260 employees, more than 20 middle and senior management staff, more than 10 professional and technical personnel, annual production capacity of 100,000 tons. Main products: flat steel, S690Q chemical composition steel pipe, steel plate, section steel, steel structure processing parts, etc. We also accept incoming materials and annealing processing.
ASTM A36 steel channel is hot-rolled, low carbon steel section with good properties including welding, machinability and ductility. A36 structural S690Q chemical composition channel have two types of sizes: UPN & UPE - tapered flanges and parallel flanges respectively. If you can't find the specific size in the table below, bespoke channel dimensions are available.
Boiler steel refers to the special steel used to manufacture pressure components of steam boilers, such as steam drums. The boiler steel mainly means boiler steel plates and seamless boiler steel pipes. Boiler components not only bear pressure loads but are also heated by direct fire, so the requirements on the chemical composition and mechanical properties of boiler steel, S690Q chemical composition are strict. In the chemical composition of boiler steel, S690Q chemical composition, sulfur and phosphorus are strictly controlled. Tensile strength, yield point, elongation, impact energy value and 180 ° cold bending are required to be tested in boiler steel mechanical properties. In addition, strain aging impact test is also required for boiler steel. The quality control of boiler steel is slightly higher than that of pressure vessel steel.
Since the welding process is often used in the fabrication and processing of steel structures, it is very important for low-alloy high-strength steels of such purpose to be welded using the arc welding process that is widely used in thin thickness plates and steel strips. Yes, the welding seam of the steel structure should have the required strength and toughness, so as to withstand the most unfavorable conditions for the intended use. At present, the development of S690Q chemical composition, low-alloy high-strength steels is carried out simultaneously with the development of various welding processes. Most low-alloy high-strength steels can be welded well.
SS400 is a low carbon steel with no specified carbon content. According to its mechanical properties, it is similar to S690Q chemical composition ASTM A36, which is widely used in engineering and industrial applications. The cost of JIS SS400 steel angle steel structure is low, and it has good performance in major projects. SS400 angle steel description:Item: SS400 angle steel. S690Q chemical composition Standard: JIS G3101-2004. Technology: hot rolled. Type: equal & unequal. Surface: black or galvanized. Length: 6 m, 9 m, 12 m or per your request. Equal angle: Size: 20 × 20 mm to 200 × 200 mm. Thickness: 3 to 20 mm. Length: 6 m, 9 m, 12 m or per your request. Unequal angle: Size: 30 × 20 mm to 250 × 90 mm. S690Q chemical composition Thickness: 3 to 10 mm. Length: 6 m, 9 m, 12 m or per your request.
