A high strength low alloy steel is a carbon steel that has a small amount of alloying elements added to its chemical composition.Alloying elements are mainly used to increase the strength of steel.High-strength low-alloy steel can provide higher strength than carbon steel, in addition, it has higher toughness.Alloying elements also improve the corrosion resistance of steel.
High strength low alloy steels are manufactured in a similar way to other types of steel.
Iron ore and coal are combined in a furnace, and then the smelting material burns off some of the impurities. Depending on the grade of high strength low alloy steel, different amounts and types of alloying elements are then added to the molten mixture. Once the chemistry is in place, several additional steps are performed to ensure the lowest levels of contamination in the high strength low alloy steel. The steel is then solidified into large rectangular ingots, and finally the high strength low alloy steel ingots are machined to final size.
