w16x67 hot rolled america standard size h beam astm a572

Chemical composition: A572 is a low-alloy high-strength steel. Taking A572Gr50 as an example, the carbon (C) content is generally 0.27% - 0.35%, the silicon (Si) content is 0.93% - 1.20%, the manganese (Mn) content is 0.80% - 1.10%, and the impurity content such as phosphorus (P) and sulfur (S) is strictly controlled, usually not exceeding 0.03%.

Mechanical properties: The yield strength of A572 steel is relatively high. For example, the yield strength of A572Gr50 is ≥345MPa, the tensile strength is between 490 - 600MPa, and the elongation can reach 22% - 35%. This enables it to withstand large loads, and at the same time has good deformation resistance and toughness, can effectively buffer energy, avoid sudden fracture, and can meet the requirements of various complex engineering environments.

Cross-section size: In "W16x67", "W16" means that the web height of the steel section is about 16 inches (about 406.4mm), and "67" means that the weight per foot is about 67 pounds (about 99.7kg/m). According to the relevant American standards, the specific dimensions are usually about 400mm web height, about 170mm flange width, about 9.5mm web thickness, and about 15.5mm flange thickness, but the actual dimensions may vary slightly due to production.

Sectional characteristics: It has a large section moment of inertia and section modulus, and its bending resistance around the strong axis (web direction) and the bending resistance around the weak axis (flange direction) are relatively strong, which can effectively resist bending deformation and provide good bearing capacity for the structure.

Processing performance: W16x67 steel made of A572 material has good processing performance and can be processed by cutting, drilling, bending and other processing operations.

Welding performance: Good weldability, commonly used welding rods are E70XX series, etc. Suitable for arc welding, gas shielded welding and other welding processes.

H-beam steel for construction: commonly used in frame structures of high-rise buildings, industrial plants, warehouses, etc., as load-bearing components such as beams and columns, it can withstand large loads and provide stable support for buildings.

H-shaped steel for bridges: can be used to build bridge piers, abutments, beams and other structural components of bridges. Its high strength and good toughness can withstand various loads during the use of bridges, including vehicle loads, wind loads, etc.

H-beam for machinery: some heavy machinery equipment brackets, bases and other structural parts will also use W16x67 steel made of A572 material to meet the equipment's requirements for strength and stability.
