Plate
Plate is steel that is generally more than three-sixteenths inch thick and 48 inches wide. It can be made on either a coiled plate mill, up to one-inch thick, or a discrete plate mill. The coiled plate, or discrete plate, is then cut into sections for specific end uses.
Applications and markets
For plate to be utilized, it must be further processed after shipment from the steel mill. This processing may be preformed by service centers, plate processors, fabricators or original equipment manufacturers (OEMs). Four processes account for the majority of this additional processing: quenching and tempering, forming, thermal-cutting and welding.

Commodity steel plate is used in a variety of applications, such as storage tanks, ships and railcars, large diameter pipe and machinery parts. More specialized steel plate, such as high-strength, low-alloy, heat-treated or alloy plate, can have superior strength and performance characteristics for particular applications such as the manufacture of construction, mining and logging equipment; pressure vessels and oil and gas transmission lines; and the fabrication of bridges and buildings. Quenched and tempered plate is harder and stronger and can be used in products, such as military armor and hard rock mining equipment.

Products
The physical properties of steel can vary depending on the chemistry of the plate. Our plate specification guide outlines the specific chemistries and mechanical properties of some commonly used plate steels. It also provides the capabiltiies overview of our three plate producing faciltiies in the United States - ArcelorMittal Burns Harbor in Indiana, and ArcelorMittal Coatesville and ArcelorMittal Conshohocken in Pennsylvania.
