W Beam ASTM A36 A992 W6X20 H Beam Steel

"W" stands for the wide flange H-beam series; "6" stands for the web height of about 6 inches, and "20" stands for the weight of each foot of steel of about 20 pounds.

The section height H of W6X20 steel is about 152.4mm, and the flange width B is about 152.4mm (the actual size may vary slightly depending on the manufacturer and standard).

Dimensions
The specific dimensions of W6X20 H-beam are H height 157mm, B width 153mm, t1 (web thickness) is 6.6mm, t2 (flange thickness) is 9.3mm, and r (fillet radius) is 7.6mm.

Material Features
 

Chemical composition: It belongs to carbon structural steel, with carbon content ≤0.25%, silicon content ≤0.4%, manganese content 0.8% - 1.2%, phosphorus content ≤0.04%, and sulfur content ≤0.05%.

Mechanical properties: yield strength is about 250MPa, tensile strength is 400-550MPa, elongation ≥20%. It has high strength and toughness, can withstand certain loads and impacts, has good weldability, is easy to process and connect, and is suitable for general construction and structural purposes.

Chemical composition: It belongs to low alloy steel, and the main elements are carbon, silicon, manganese, phosphorus, sulfur, etc. Among them, carbon can improve the strength and hardness of steel, silicon and manganese help to improve toughness and corrosion resistance, and phosphorus and sulfur need to be controlled within a certain range to ensure quality.

Mechanical properties: The yield strength reaches 345MPa, and the tensile strength reaches 448MPa. It has high strength and good ductility. It can adapt to different stress conditions while ensuring structural safety. It is especially suitable for building structures and machinery manufacturing fields with high strength requirements.

Construction field: widely used in the construction of frame structures, frame-shear wall structures, such as residential buildings, office buildings, shopping malls, etc., and also used in the construction of steel structure bridges, and can be used as the main beam, cross beam and supporting structure of the bridge and other key parts.

Machinery manufacturing field: often used in the supporting structure of heavy machinery such as excavators, loaders, cranes, etc., can withstand large loads and impact forces, and ensure the stability and safety of the machinery.
