Low Alloy High Strength Structural Steels
Low alloy high strength structural steel is a steel that adds a small amount of one or more alloying elements to improve the strength, corrosion resistance, wear resistance or low-temperature impact toughness of general carbon steels.
These steels includes Q345, Q390, Q420, Q460, Q500, Q550, Q620, and Q690.
Weather Resistant Structural Steels
Weather resistant structural steel is a steel that increases the resistance to atmospheric corrosion by adding a small amount of alloying elements such as Cu, P, Cr, Ni, etc. to form a protective layer on the basic surface of the metal.
These steels include Q235NH, Q265GNH, Q295NH, Q295GNH, Q310GNH, Q355NH, Q355GNH, Q415NH, Q460NH, Q500NH, Q550NH.
