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.
LOW CARBON PLATE STEEL
Low Carbon Plate Steel is manufactured to three separate carbon ranges that relate to thickness and end use requirements. Plates 3/4″ and lighter are produced to the lowest carbon range (0.10-0.20) for maximum cold forming and welding properties. 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 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.
MEDIUM CARBON PLATE STEEL
Medium Carbon Plate Steel in the (.40-.50) carbon range is silicon killed and higher carbon for improved strength. Light and medium thicknesses can also be heat treated for greater strength. Machinability is good, but forming and welding properties are limited.
STRUCTURAL QUALITY STEEL
ASTM A36 PLATE STEEL is a structural quality product designed for use in welded, bolted, or riveted fabrications such as oil rigs, buildings and bridges. Produced with a min. 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.
T-1 plate provides good formability, high strength, toughness at subzero temperatures, and weldability with minimal preheat requirements. Stocked in 3/16 through 1-1/2″ thick.
Abrasion resistant steel is produced to a special carbon-manganese specification, developed specifically for applications requiring superior wear resistance, and will usually outlast ordinary steel grades by a wide margin.
PRESSURE VESSEL QUALITY STEEL
Pressure Vessel Quality steel plate is produced to tightly controlled ASTM standards in order to provide superior grade of carbon steel plate designed specifically for pressure vessel and boiler applications but also suited to a variety of less demanding commercial applications.
PVQ plate is subject to a specified series of tests to insure conformance to standards.
ASTM A515 STEEL (GRADE 70) has greater strength than A285 and intended for intermediate and high temperature boilers and pressure vessels. It is a silicon killed, coarse grained steel that requires careful welding techniques
ASTM A516 STEEL (GRADE 70) is similar to A515 but is intended for lower temperature applications. It is also silicon killed, but has a finer grain and improved notched toughness. Stocked in an as rolled condition and charpy tested.
ASTM A572 STEEL (GRADE 50) INX-EXTEN is available with. 50,000 psi min strength level. It is moderately priced and offers high strength in combination with good formability and weldability. Atmospheric corrosion resistance is about equal to plain carbon steel. Conform to SAE J41 0 and Grade 950X.
STEEL PLATE COILS
Low carbon, black, and pickled and oiled steel coils are available from 3/16″ to 1/2″ thick, up to 84″ wide for precision roller levelling and cutting to standard and special lengths up to 480″.
Ultrasonic Testing and ASS certification available upon request.
Accepted trade practice provides for invoicing of all Plate product based on the theoretical weight of the ordered size, using a density of .2836 pound per cubic inch rounded to the nearest full pound per piece.
