An October 2018 release from the World Steel Association predicted a small increase (1.4%) in global steel demand for 2019. That projection proved to be too conservative as the same report (pictured above) in October 2019 details increases of 3.9 percent due in large part to an unexpected rise in demand in China.. The year was challenging for the vast majority of worldwide economies, but ASTM A572 Grade50,55,60 HSLA Structural Steel Plate-AGICOASTM A572 Carbon Steel Plate. ASTM A572 Specification refers to High-Strength Low-Alloy Steel Plate for structural building, among the 5 steel grades of 42, 50, 55, 60 and 65, Grade 50 is one most common steel in applications where need more strength and less weight, use steel plate of this grade other than ordinary carbon steel will make the steel structure with same steel strength but
ASTM A572 steel plate is made of A572, a High-Strength Low-Alloy, Columbium-Vanadium Structural Steel. There are five grades of high-strength low-alloy structural steel shapes, plates, sheet piling, and bars. Grades 42 , 50 , and 55  are best for riveted, bolted, or welded structures.
