A992 A572 grade 50 high strength U channel carbon structural steel

A992 A572 grade 50 high strength U channel carbon structural steel, as an American standard low alloy structural steel, is produced by hot rolling process with a yield strength of ≥ 345MPa and a carbon content controlled below 0.23%. The strength is improved by adding microalloying elements such as niobium and vanadium. Typical specifications include a leg width of 88.9mm, waist thickness of 15.2mm, and a cross-sectional modulus of 67.4cm³ for C15 × 50, making it particularly suitable for building curtain wall keels and mechanical equipment load-bearing frames.

A992 A572 grade 50 high strength U channel carbon structural steel has excellent cold bending performance (bending radius ≤ 2 times thickness) and welding adaptability (carbon equivalent ≤ 0.45%), and is widely used in steel structure corridors, industrial platform supports, and other scenarios. When purchasing, it is necessary to focus on checking the leg end perpendicularity tolerance (≤ 1.5 °) and impact toughness report (-20 ℃ impact energy ≥ 27J) in ASTM A6 standard.
