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. This enhances weldability and choice of coatings, since these steels exhibit neither weld zone softening nor grain coarsening. These grades are particularly suitable for structural components such as suspension systems
Leeco ® Steel carries a deep inventory of carbon or mild steel plate as well as High Strength Low Alloy or HSLA steel plate. HSLA boasts a higher strength, lower weight and good machinability and ductility compared to conventional mild carbon steel grades. HSLA structural steels are manufactured to meet specific mechanical properties, such as hardness, strength, corrosion resistance
Typically, HSLA steels are low carbon steels with up to 1.5% manganese, strengthened by small additions of elements, such as columbium, copper, vanadium or titanium and sometimes by special rolling and cooling techniques.
HSLA steels are available today with traditional ferritic pearlitic, bainitic, martensitic and multiphase microstructures, each available in hot or cold rolled steels. The yield strength of contemporary HSLA steels ranges from 260 MPa to over 1000 MPa. Typically, Mo is used in HSLA steel when the yield strength must be above 550 MPa, or a particular microstructure is demanded.
High Strength Low Alloy (HSLA) steels are very strong, highly formable, and easy to weld. They resist corrosion and rust better than plain carbon steels. HSLA is a type of steel that is more resistant to corrosion and rust than carbon steels. HSLA Steels are made to specific mechanical properties rather than a chemical composition.
High strength, low alloy (HSLA) steels have nearly the same composition as plain carbon steels. However, they are up to twice as strong and their greater load bearing capacity allows engineering use in lighter sections. Their high strength is derived from a combination of grain refinement; precipitation strengthening due to minor additions of vanadium, niobium, or titanium; and modifications
ASTM A 572 (gr50/gr60/gr65) is a high strength, low alloy steel that offers greater strength than plain carbon steel plate, plus ductility, weldability, formability, toughness and fatigue strength. A572 meets a minimum strength requirement (dependent on grade) and
HSLA tubing provides a higher strength over normal carbon steel tubing with the addition of alloying elements such as columbium, vanadium, molybdenum and titanium without increasing the carbon or wall thickness of the steel giving it a high strength to weight ratio.
The alloy is more than carbon steel during normal production methods, which is called alloy steel. Alloy less than 3.5%, it is called low alloy steel; alloy between 3.5% and 10%, it is called medium alloy steel; alloy more than 10%, it is called high alloy steel.
The development and use of high strength low alloy (HSLA) steels has been driven by the need to reduce costs, the higher strength compared with a conventional carbon manganese steel enabling thinner and lighter structures to be erected.
High strength low alloy (HSLA) grades ApplicationTransmission component BILSTEIN’s micro alloyed steel grades offer minimum yield strength levels from 260 to 420 MPa with excellent cold formability at all strength levels.
They resist corrosion and rust better than plain carbon steels. HSLA steels are made to provide specific mechanical properties rather than specific chemical compositions. Use cold rolled high strength low alloy steel coils in cars, trucks, cranes, bridges, and other structures where their high strength to weight ratio is most cost effective.

Higher levels of carbon tend to form martensite or bainite in the microstructure of as rolled steels, although some of the higher strength low alloy steels have carbon contents that approach 0.30%. The required strength is developed by the combined effect of:
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 to specific mechanical properties.
