Applications of Low Alloy Steel Plate: The A36 steel plate is extensively used in a variety of industries.
The A572 is widely used in structural applications, including bridges, buildings and construction equipment and more.
The A656 steel plate is used in construction equipment, crane booms, truck frames and general fabrication.
The A573 plate is used to manufacture storage tanks where atmospheric conditions require improved notch toughness.
The A283 plate features low and intermediate tensile strength carbon steel plate of structural quality.

High Strength Low Alloy or HSLA steel plates, provide greater environmental corrosion resistance and are stronger than convention carbon steel. HSLA is also very ductile, highly formable and easy to weld. HSLA steels are not typically made to meet a certain chemical composition, instead they are known to meet specific mechanical properties. The HSLA specification is intended primarily for use in structural members, where savings in weight and added durability are critical.

BBn Steel carries an extensive supply of HSLA steel plate in a variety of grades that meet the worldwide standards. HSLA can be used in truck frames, brackets, crane booms, rail cars and other comparable applications. Taking ASTM A36 as an example, ASTM A36 is used for general purpose structural, machinery parts, frames, fixtures, automotive and agricultural implements and equipment, brackets, stakes, ornamental works, forgings, base plates, gears, cams, sprockets, jigs, rings, templates, fixtures, bearing plates, tanks, bins, various parts obtained by flame cutting, and miscellaneous non-critical applications that involve mild cold bending, mild hot forming, punching, machining, and welding.

High strength low alloy steels include many standard and proprietary grades designed to provide specific desirable combinations of properties such as strength, toughness, formability, weld-ability, and atmospheric corrosion resistance. These steels are not considered alloy steels, even though their desired properties are achieved by the use of small alloy additions. Instead, HSLA steels are classified as a separate steel category, which is similar to as-rolled mild-carbon steel with enhanced mechanical properties obtained by the addition of small amounts of alloys and, perhaps, special processing techniques such as controlled rolling and accelerated cooling methods. This separate product recognition of HSLA steels is reflected by the fact that HSLA steels are generally priced from the base price for carbon steels, not from the base price for alloy steels.
