Introduction
Plate is steel that is generally heavier than 3/16-inch-thick and greater than 48 inches wide. At ArcelorMittal, plates are produced on a discrete plate mill. If required, further heat treating can be utilized to tailor the physical properties of the plate to meet various requirements. This includes thermal-mechanical controlled processing (TMCP), normalizing, and quench and tempering. The plate can be cut into sections for specific end uses as needed.
Carbon and high-strength low alloy (HSLA) steel plate is used in a variety of applications, such as storage tanks, ships and railcars, large diameter pipe, wind towers, machinery parts and offshore structures. More specialized steel plate, such as alloy plate, can have superior strength and performance characteristics for particular applications. These applications could include the manufacture of construction, mining and logging equipment, pressure vessels, the fabrication of bridges and buildings, military armor and hard rock processing equipment.
