Low alloy high-strength steel plate

Low alloy high strength steel is a kind of engineering structural steel developed on the basis of carbon structural steel by adding a small amount of Mn, Si and a small amount of Nb, V, Ti, Al and other alloying elements. The so-called low alloy means that the total amount of alloying 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 alloy elements as possible to obtain as high comprehensive mechanical properties as possible, so as to meet the use and low cost.

The size range of Low alloy high strength steel plates we can supply is : T: 5-500mm, W: 900-4800mm, L:3000-25000mm.
