A572 Steel
High-strength low-alloy
Family of high-strength, low-alloy (HSLA) structural steels (ASTM A572 / A572M), with minimum yield strengths between 290 and 450 MPa. Microalloyed with niobium, vanadium, titanium, or nitrogen; high strength-to-weight ratio, good weldability, and easy fabrication. For welded, bolted, or riveted structures, buildings, towers, platforms, frames, and heavy machinery.
