high-strength low-alloy steel


high-strength low-alloy steel

[′hī ‚streŋkth ¦lō ¦al‚ȯi ′stēl] (metallurgy) Steel containing small amounts of niobium or vanadium and having higher strength, better low-temperature impact toughness, and, in some grades, better atmospheric corrosion resistance than carbon steel. Abbreviated HSLA steel.

high-strength low-alloy steel

Steel having a chemical composition specifically developed to impart higher mechanical property values and, in some cases, greater resistance to atmospheric corrosion than is obtainable from conventional carbon steels.
