Leading Manufacturer, Supplier & Retailer of HIGH STRENGTH LOW ALLOY (HSLA) STRUCTURAL STEEL PLATE, PRESSURE VESSEL (PVQ) STEEL PLATE, Tempered Steel Plate, CATERPILLAR SPEC STEEL PLATE and EN STANDARD STEEL PLATE.

HIGH STRENGTH LOW ALLOY (HSLA) STRUCTURAL STEEL PLATE

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. Leeco steel carries an extensive supply of hsla steel plate in a variety of grades that meet both the us and canadian standards. Hsla can be used in truck frames, brackets, crane booms, rail cars and other comparable applications. Talk with one of our sales representatives.

EN STANDARD STEEL PLATE

Leeco Steel offers structural steel plate that meets the European standard for structural steel. We carry EN 10025: 2004, in grades of S235, S275, S355, S420, S690 and S890. The EN 10025: 2004 encompasses a broader range of structural metallic products and divides them into six basic categories: General Purpose Steels Non-alloy Structural Steels Normalized Normalized-Rolled Weldable Fine Grain Structural Steels Thermo Mechanically-Rolled Weldable Fine Grain Structural Steel Atmospheric Corrosion Resistant Structural Steel ("Weathering Steel") High Strength, Quenched and Tempered Structural Steel Within these six categories are individual grades. The foundation of each grade within the EN 10025 standard is the material’s tested yield strength measured in megapascals (1 MPa = .145 ksi). Each structural steel grade begins with an "S" and is followed by suffixes that represent variations in the specific requirement for that structural application.

Abrasion Resistant Steel Plate

Abrasion Resistant (AR) steel plate is typically made in the as-rolled condition. These typesgrades of steel plate products have been developed specifically for long service life in harsh conditions. AR products are suitable for a variety of applications in areas such as miningquarrying, conveyors, material handling and construction, and earthmoving. Designers and plant operators choose AR plate steel when striving to extend service life of critical components, and reduce the weight of each unit put into service. The benefits of employing wear-resistant plate steel in applications involving impact andor sliding contact with abrasive material are immense. Steel plate for use in abrasive conditions is not typical because it is not governed by any ASTM code or spec. Many steel plate manufacturers produce their own brand of abrasion resistant steel and these are usually distinguished by a brand name followed by the hardness of the steel which is measured in Brinell units

HIGH CARBON STEEL PLATE

Carbon plate steel’s main interstitial alloying constituent is carbon, hence the name, at a variety of concentrations. As carbon percentage content rises, steel has the ability to become harder and stronger through heat-treating. High carbon steel is very strong. Low carbon steel is more malleable and ductile and is easier to cold form. Leeco Steel maintains a solid inventory of lowhigh carbon, non structural steel plate at each of our distribution centers.
