A36 W40x149 W40x167 w wide flange beam
Product description of W40×149/W40×167 h beam wide flange
"W40" series: indicates that the section height is 40 inches (about 1016mm), and the suffix number is the weight (pounds/foot).
W40×149 wf steel beam: weight 149 pounds/foot (about 222kg/m).
W40×167 h beam wide flange: weight 167 pounds/foot (about 249kg/m).
Flange width: about 300-350mm.
Web thickness: 14-20mm, flange thickness 12-18mm, cross-sectional area about 280-350cm².
Moment of inertia: about 35,000-45,000cm⁴ (excellent bending resistance).
A36 is a low-carbon structural steel that complies with the ASTM A6/A36 standard and is suitable for construction and industrial load-bearing structures.
Performance characteristics of A36 h type beam
Mechanical properties of A36 h section steel beam Yield strength: ≥250MPa (36ksi), tensile strength 400-550MPa.
Elongation: ≥20%, excellent toughness, suitable for dynamic load scenarios.
Impact toughness: ≥27J (V-notch) at room temperature, ensuring stability in low temperature environments.
Chemical composition of A36 h shaped steel Low-carbon design: carbon content ≤0.25%, silicon ≤0.40%, manganese 0.80-1.20%.
Impurity control: phosphorus ≤0.04%, sulfur ≤0.05%, improving weldability and corrosion resistance.
Process advantages of A36 h section steel
Hot rolling forming: Uniform grain refinement and reduction of internal residual stress.
Weldability: Low hydrogen electrodes (such as E7018) are recommended, and the welding heat input needs to be controlled within 2kJ/mm.
Application of A36 W40×149/W40×167 w shape beam
Building structure: Used for high-rise building frames and large-span factory beams to support medium to heavy concentrated loads.
Bridge and transportation engineering: Suitable for highway bridges and railway bridge main beams to meet the bending requirements of spans of 30-50m.
Industrial equipment: As port crane track beams and large equipment bases, it can withstand long-term fatigue loads.
