What is S960QL steel properties

Oxygen (O) is a harmful element in steel such as S960QL steel properties. Although manganese, silicon, iron and aluminum are added to deoxidize the steel at the end of steelmaking, they can not be removed completely. During the solidification of molten steel, the reaction of oxygen and carbon in the solution will produce carbon monoxide, which can cause bubbles. Oxygen mainly exists in the form of FeO, MnO, SiO2, Al2O3 and other inclusions in the steel, which reduces the strength and plasticity of the steel. Especially, it has serious influence on fatigue strength and impact toughness.

Low alloy high strength steel is a kind of engineering structural steel developed by adding a small amount of Mn, Si and a small amount of Nb, V, Ti, Al and other alloy elements on the basis of carbon structural steel, S960QL steel properties. The so-called low alloy means that the total amount of alloying elements in steel is less than 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 requirements of use and low cost.

Lopes, President of the Brazilian Iron and Steel Association, pointed out that at present, increasing S960QL steel properties and so on steel exports would be the best choice for Brazilian steel producers. The Association has made a series of proposals to the Brazilian government to support the economic recovery. Lopes revealed that the Association is seeking to increase the export tax rebate proportion of the steel industry from the current 0.1% to 5%, which will give related products a price advantage of 7% when exporting, and the export volume is expected to increase by 20%.
