Overview


Low alloy high strength is steel added with certain alloying elements accounting for less than 5% in the melting process. It can significantly improve the strength of steel, and the three major indexes of the steel structure as strength, stiffness and stability can give full play. Due to different quality, It is divided into A, B, C, D, E grade.
