T-1 plate provides good formability, high strength, toughness at subzero temperatures, and weldability with minimal preheat requirements. yield of 36,000 psi, A36 plate can be used in the construction of a variety of lightweight structures and equipment where good welding properties are important.ĪSTM A514B (T♱ & TYPE A REG) STRUCTURAL QUALITY STEEL is a quenched and tempered high strength alloy steel designed for construction type applications and produced to minimum mechanical properties.

STRUCTURAL QUALITY STEELĪSTM A36 PLATE STEEL is a structural quality product designed for use in welded, bolted, or riveted fabrications such as oil rigs, buildings and bridges. Machinability is good, but forming and welding properties are limited. Light and medium thicknesses can also be heat treated for greater strength. Medium Carbon Plate Steel in the (.40-.50) carbon range is silicon killed and higher carbon for improved strength. Plates over 1 1/2″ have carbon increasing to (0.20-0.33), this is a killed steel that provides the best combination of strength, weldability, and structural soundness. Sizes 3/4″-1 1/2″ the carbon range is (0.15-0.25) which gives improved machining, while retaining its forming and welding properties.

Plates 3/4″ and lighter are produced to the lowest carbon range (0.10-0.20) for maximum cold forming and welding properties. Low Carbon Plate Steel is manufactured to three separate carbon ranges that relate to thickness and end use requirements. Commercial and Specification Grade Steel Plates are stocked to meet a variety of end use requirements that range from the most unsophisticated storage bin to such highly critical applications as Cryogenic Pressure Vessels.
