HSLA Steel Sheet
Low alloy steel (HSLA) is referred to alloy elements less than 3.5% of the total. Relative to carbon steel, low alloy steel, on the basis of carbon steel in order to improve one or more performances of steel is added one or several alloy steel elements. The alloy is more than carbon steel during normal production methods, which is called alloy steel. Alloy less than 3.5%, it is called low alloy steel; alloy between 3.5% and 10%, it is called medium alloy steel; alloy more than 10%, it is called high alloy steel.
