Astm a992 w8x35 hot rolled alloy steel h-beams

"W" stands for the wide flange H-beam series, "8" means the section height is about 8 inches, or 203.2mm, and "35" means the weight of each foot of the steel is about 35 pounds, which is about 52.16kg per meter after conversion.

Chemical composition: It is a low-alloy high-strength steel with a carbon content of ≤0.23% and a silicon content of ≤0.40%. It also contains a small amount of alloy elements such as chromium, copper, vanadium, molybdenum, and nickel.

Mechanical properties: The yield strength is not less than 345MPa (50ksi), the tensile strength is high, it has good toughness and ductility, and the elongation and other indicators can meet the seismic and impact resistance requirements of general structures.

It is usually produced by hot rolling process. After the steel billet is heated to a high temperature, it is rolled through multiple rollers to gradually make the steel reach the required shape and size. During the hot rolling process, the internal structure of the steel is optimized, giving it better mechanical properties. At the same time, during the production process, the chemical composition and rolling parameters will be strictly controlled to ensure that the steel meets the relevant standards and requirements of A992 material.

High strength: It can withstand large loads and is suitable for building structures and engineering fields with high strength requirements. It can reduce the use of steel and reduce the deadweight of the structure.

Good welding performance: It is easy to weld, the welding quality is easy to ensure, and it can be easily assembled and connected on site to form a stable structural system.

Good corrosion resistance: Due to the effect of alloy elements, its corrosion resistance is better than that of ordinary carbon steel. It has a longer service life in some harsh use environments, such as humid and corrosive media.

Construction engineering: It is commonly used in the structural framework of high-rise buildings, large commercial buildings, industrial plants, etc. As the main load-bearing components such as beams and columns, it can provide reliable support for buildings and withstand the deadweight, wind loads, earthquake loads, etc. of buildings.

Bridge construction: It is one of the commonly used materials for building bridges. It can be used to manufacture structural components such as the main beam, cross beam, and piers of bridges. It can withstand various loads during the use of bridges and ensure the safety and stability of bridges.

Other fields: It is also widely used in the foundation frame, tower structure, offshore platform and other fields of some large-scale mechanical equipment, and can meet the requirements of these structures for high strength, high toughness and good corrosion resistance.
