About products
Low alloy high strength steel is a kind of engineering structural steel developed by adding a small amount of Mn, Si, Nb, V, Ti, Al and other alloy elements on the basis of carbon structural steel. The so-called low alloy means that the total amount of alloy elements in steel does not exceed 3%. High strength is relative to carbon engineering structural steel. The development principle of low alloy high strength steel is to use as few alloying elements as possible to obtain as high comprehensive mechanical properties as possible, so as to meet the purpose of use and low cost. Low alloy high-strength steel can meet the requirements of large bearing capacity of various structures (such as large bridges, pressure vessels, ships, etc.) in engineering, and at the same time, it is required to reduce the dead weight of structures, improve reliability, and save materials and resources. This kind of 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 this kind of steel can obtain high strength without complex treatment process or even heat treatment, which greatly reduces the quality of engineering structures, it is used to replace general carbon structural steel.
