Quenched & Tempered Steel Plate
Alloy quenched and tempered (Q&T) steel plate is a heat-treated alloy steel engineered to deliver an exceptional balance of high strength, toughness and wear resistance in demanding environments. The process involves heating the steel to a high temperature and rapidly cooling it, known as quenching, before reheating it to a controlled temperature, known as tempering, to improve toughness and reduce brittleness. As a result, Q&T plate offers greater resistance to impact, abrasion and fatigue than many conventional structural steels, making it a preferred choice for applications where durability and weight reduction are critical.
This same heat-treatment process is also used to produce many abrasion-resistant (AR) steel grades, though Q&T steels are typically selected for their combination of strength, toughness and structural performance. Commonly used in mining, construction, material handling, transportation, energy and heavy equipment manufacturing, Q&T steel plate is found in crane booms, truck frames, buckets, pressure vessels, trailers and other high-performance structural components. Grades such as ASTM A514, A710 and A829-4140 are frequently specified when engineers need a strong, weldable and machinable steel capable of withstanding severe service conditions.
Leeco® Steel maintains one of North America's largest inventories of alloy Q&T steel plate, offering a wide range of grades, thicknesses and value-added processing services including cutting, beveling, drilling and shot blasting. With extensive inventory, technical expertise and nationwide distribution, Leeco helps customers source the right Q&T plate solution quickly and efficiently for even the most demanding applications.
