ASME SA572 Grade 50  low alloy steel plates are intended for riveted, bolted, or welded structures. This material is a high-strength low-alloy columbium-vanadium structural steel. SA572 Grade 50 alloy provides a minimum yield point of 345 MPa[50ksi] in thicknesses up to 15in. [380 mm]. It is equal to ASTM A572 Grade 50.
