High strength low alloy. Refers to steels used in pipelines, engineering and construction of higher strength and corrosion resistance than carbon steel. Their properties are obtained by small additions of alloying elements such as manganese, molybdenum and vanadium.
High Strength Low Alloy, a very strong steel
High Strength Low Alloy Steel. Steel with relatively high strength and impact properties. The carbon level is low and the alloying additions are significantly less than 5 weight percent.
High strength low alloys: a type of alloy steel that provides better mechanical properties or greater resistance to corrosion than carbon steel
