A572GR50 h beam wide flange material characteristics
Chemical composition
Carbon (C) ≤0.20%, manganese (Mn) ≤1.50%, containing trace amounts of alloying elements such as niobium (Nb) and vanadium (V) to optimize strength and toughness. Sulfur (S) ≤0.05%, phosphorus (P) ≤0.04%, reducing the risk of cold brittleness and hot brittleness.
Core Advantages
High strength and toughness balance: yield strength ≥345MPa, tensile strength 490-600MPa, elongation ≥22%, with both load-bearing capacity and plastic deformation adaptability.
Excellent welding performance: low carbon content (≤0.20%), low welding crack tendency, supporting arc welding, submerged arc welding and other processes.
GNEE production process and quality control
Manufacturing process
1. Hot rolling forming, using controlled rolling and controlled cooling process to refine grains and improve comprehensive performance.
2. Normalizing/tempering treatment eliminates residual stress and optimizes the toughness of the welding area.
Testing standards
1. UT flaw detection (ASTM A578) ensures that there are no defects such as cracks and slag inclusions inside the material.
2. Impact test (ASTM A370) verifies the ability to resist brittle fracture in low temperature environment.
