ASTM A572 grade 50 high strength structures carbon steel H beam

ASTM A572 grade 50 high strength structures carbon steel H beam adopts niobium vanadium microalloying design (carbon equivalent ≤ 0.45%), with a yield strength of ≥ 345MPa. After hot rolling, the section inertia moment is optimized (such as W12 × 65 specification web thickness of 11.4mm, flange width of 165.1mm), significantly improving the bending performance.

ASTM A572 grade 50 carbon steel H beam is designed specifically for large-span building beams, suitable for heavy-duty scenarios such as sports stadium trusses and industrial plant main beams. When purchasing, it is necessary to verify the ASTM A6 standard flange inclination (≤ 1:16) and Z15 anti laminar tear certification.
