Corten Structural Steel

Weathering-resistant structural steel is a new type of steel developed on the basis of low-alloy high-strength structural steel, inherited from the low-alloy high-strength structural steel itself has excellent cold and hot working performance of certain properties, such as: good plastic change and toughness.

Weathering structural steel is divided into high weathering steel and welded weathering steel, the grade of such steel by the letter Q on behalf of the "yield strength" and "high weathering" letter GNH, "weathering" letter NH and the quality grade of the steel. NH and the quality grade of steel (A, B, C, D, E) order, such as Q355GNHC, Q460NHD.

High weathering steel, according to the standard provisions of a total of Q295GNH, Q355GNH, Q265GNH, Q310GNH four grades; welded weathering steel, according to the standard provisions of a total of Q235NH, Q295NH, Q355NH, Q415NH, Q460NH, Q500NH, Q550NH seven grades, and its chemical composition (conventional C, Si, Mn.), S, P five elements and Tu460NHD, S, P five elements and Tu, Cr) melting analysis than the corresponding grade of low-alloy high-strength structural steel chemical composition melting analysis to be strict, especially C, S, P element content is low, mechanical properties are basically equivalent to the corresponding grade of low-alloy high-strength structural steel chemical composition and mechanical properties, such as Q460C. steel quality grade is only related to the impact toughness of steel impact toughness test temperature and the value of the impact work.

Welded weathering steel applications are mainly concentrated in vehicles, bridges, containers, buildings or other structural components and other structural use, compared with high weathering steel, has relatively good welding performance. Because of its excellent atmospheric resistance and durability, the application in the field of steel bridges, has been emphasized and began to promote.
