What is the difference between A572GR50 and A992 materials for W14x82 H-beam?
A572GR50 h section steel beams material
Strength and toughness: yield strength ≥345MPa, tensile strength 450-550MPa, elongation ≥18%, with both high strength and good plasticity, suitable for conventional load structures.
Chemical composition: Contains Mn (1.35-1.65%), Nb (0.005-0.05%), V (0.01-0.05%), and refines grains through controlled rolling and controlled cooling process to improve low-temperature toughness.
Corrosion resistance: A dense oxide film can be formed on the surface, suitable for humid or mildly corrosive environments.
A992 h beam steel structure material
Strength and toughness: yield strength ≥414MPa, tensile strength 485-620MPa, taking into account high strength and excellent weldability, suitable for high-rise buildings and large-span structures.
Composition optimization: Balance strength and weldability by adjusting C, Mn content and heat treatment process.
Economical: Higher strength can reduce material usage and construction costs.
W14x82 h beam material specification parameters
Section type: Wide flange H-beam (W series), flange and web width are similar, excellent bending resistance.
Naming rules: "W14" means the section height is about 14 inches (356mm); "x82" is the unit length weight (pounds/foot), corresponding to 82lb/ft (122kg/m).
