Material characteristics of A572GR50 material h beam
Chemical composition
Carbon (C) ≤0.20%, Silicon (Si) ≤0.40%, Manganese (Mn) ≤1.50%, Phosphorus (P) ≤0.04%, Sulfur (S) ≤0.05%, Niobium (Nb) 0.005~0.05%; Niobium-vanadium alloy design improves grain refinement, strength and toughness.
Mechanical properties
Yield strength: 345~470 MPa (adjusted according to thickness, higher when ≤16mm).
Tensile strength: 490~600 MPa.
Elongation: ≥22%~35% (varies with thickness).
Impact toughness (0℃): ≥45~150 J (longitudinal).
Processing characteristics
Excellent cold/hot bending forming capability, suitable for complex structure processing; outstanding welding performance, supporting a variety of welding processes (manual arc welding, submerged arc welding, etc.).
Wide Flange H Beam Specifications

Performance characteristics of W14x43/W14x48 wide flange beam
Carrying capacity: High yield strength and tensile strength, suitable for heavy-load structures (such as bridges, high-rise buildings); W14x48 h beam wide flange The flange and web are thicker, and the bending resistance is increased by about 12% compared with W14x43 wide flange h beam.
Stability: Niobium element refines the grain, enhances fatigue resistance and impact resistance, and adapts to dynamic load environment.
Weather resistance: Corrosion resistance is better than ordinary carbon steel under normal environment, and surface protection treatment is required in special environment.
Application of W14x43/W14x48 h beam wide flange
Building structure: high-rise building frame, industrial plant support column and large-span truss.
Bridge engineering: key load-bearing components such as main beams and bridge piers, especially suitable for high-load highway bridges.
Heavy machinery: crane booms, mining equipment brackets and other scenes requiring high-strength support.
Other fields: pressure vessel support parts, ship structure reinforcement (must meet specific design specifications).
