Hsla Steel Sheet

General characteristics of a1011 hsla.

Hsla steel sheet.

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. High strength low alloy steel hsla is a type of alloy steel that provides better mechanical properties or greater resistance to corrosion than carbon steel hsla steels vary from other steels in that they are not made to meet a specific chemical composition but rather specific mechanical properties. Standard specification for high strength low alloy columbium vanadium structural steel specifies five grades of high strength low alloy hsla structural steel shapes plates sheet piling and bars. Hsla steel sheet low alloy steel hsla is referred to alloy elements less than 3 5 of the total.

Hsla structural steels are manufactured to meet specific mechanical properties such as hardness strength corrosion resistance. Steels in the hsla high strength low alloy range are hardened by a combination of precipitation and grain size refining resulting in high strength with low alloy content. Astm a36 is a general purpose hsla steel. Composition hsla steels have yield strengths greater than 275 mpa or 40 ksi.

Hsla steels are made to provide specific mechanical properties rather than specific chemical compositions. Our stock range is available in heavy plates and sheets. A1011 hsla sheet steel is generally used in applications where weight reduction is a major factor as it offers a high strength at a fraction of the weight of conventional carbon sheet steel. Grades 42 290 50 345 and 55 380 are intended for riveted bolted or welded.

The hsla steels in sheet or plate form have low carbon content 0 05 to. Improved resistance to corrosion over carbon steel. They resist corrosion and rust better than plain carbon steels. There are many different grades of hsla steel available because of the variety alloying element combinations that can be used.

The chemical composition of a specific hsla steel may vary for different product thicknesses to meet mechanical property requirements. We can offer high strength steel with a tensile strength of up to 1300mpa see section on high yield steel. Masteel uk limited offers an extensive selection of high strength low alloy steel products which are available for shipping to our customers worldwide. One of the most popular types of hsla steel is astm a36.

These grades are particularly suitable for structural components such as suspension systems. The chemical composition and grade should be dependent on the intended application of the hsla steel. Leeco steel carries a deep inventory of carbon or mild steel plate as well as high strength low alloy or hsla steel plate. This enhances weldability and choice of coatings since these steels exhibit neither weld zone softening nor grain coarsening.
