5. Prospects of A588GrB steel plate: With the development of large-scale steel structure bridges towards fully welded structures and high parameters, the requirements for the safety and reliability of bridge structures are becoming more and more stringent. This not only puts forward higher requirements for designers, but also puts forward a higher level of steel plate quality, that is, it not only has high strength to meet the requirements of lightweight structure, but also should have excellent low temperature toughness, weldability and corrosion resistance etc. to meet the requirements of safety, reliability and longevity of steel structures. Traditional high-strength bridge steel not only has poor impact toughness, weldability, and fatigue properties, but also cannot resist atmospheric and seawater corrosion. Therefore, domestic and foreign material workers put forward the concept of High Performance Steel (HPS). High-performance steel mainly refers to the steel whose one or several properties of the material are improved compared with the traditional steel. In addition to higher strength, the welding performance, low-temperature toughness and especially the corrosion resistance of the steel have been greatly improved.
