ASTM A572 Grade 55 HSLA Steel
ASTM A572 grade 55 is a type of ASTM A572 steel. Cited properties are appropriate for the as-fabricated (no temper or treatment) condition. The graph bars on the material properties cards below compare ASTM A572 grade 55 to: wrought alloy steels in the same category (top), all iron alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.

A572 Gr.55 steel plate is high strength low alloy columbium-vanadium structural steel grade.Compare with A572 Gr.50, A 572 Gr55 steel has a more yield and tensile strength in project.
