Q310GNH, Q295NH, Q355NH corten steel sheet, low alloy high strength steel can meet the requirements of various structures (such as large bridges, pressure vessels, ships, etc.) in engineering. At the same time, it is required to reduce the weight of the structure, improve the reliability and save materials and resources. Low alloy high strength steel is mainly used to manufacture various engineering structures with high strength requirements, such as bridges, ships, vehicles, high pressure vessels, oil and gas pipelines, large steel structures, etc. Because low alloy high strength steel can obtain high strength without complicated treatment process or even heat treatment, the quality of engineering structure is greatly reduced. Therefore, low alloy high strength steel is commonly used to replace the general carbon structural steel.
