St52-3 steel, A709 Gr 50S bridge steel plate is low alloy high strength steel. The main characteristics of St52-3 steel are high tensile strength and yield point. St52-3 steel is used in civil construction, underground engineering, bridge structure, ocean structure, container manufacturing, automobile and machine manufacturing. Based on the principle of quality oriented, the company has established a perfect quality standard inspection system to provide customers with high-quality and low-cost steel products and after-sales services, which has been supported and praised by new and old users from all walks of life.
Perhaps this A709 Gr 50S bridge steel plate explains why Trump has warmed to the idea of constructing a border wall on the U.S. border with Mexico out of steel rather than concrete. In an interview with NPR, Tom Gibson, president and CEO of the American Iron and Steel Institute estimated that the barrier would require a hefty order of A709 Gr 50S bridge steel plate 3 million tons of steel.

Quenching and tempering (QT) is a double heat treatment process of quenching and high temperature tempering. In general, medium carbon steel and medium A709 Gr 50S bridge steel plate carbon alloy steel often need quenching and tempering treatment. Quenching and tempering can make iron and steel parts obtain a good combination of strength and toughness, with high strength, excellent toughness, plasticity, cutting performance, etc. Some A709 Gr 50S bridge steel plate alloy steel or low alloy steel must be quenched and tempered to obtain good comprehensive properties. These steels can also be called quenched and tempered steels.
