Quenched and Tempered Steel Plate
Q&T steel plate goes through the processes which strengthen and harden it. The process involves heating the plate and then rapidly cooling it to set the components into place as quickly as possible. This process is strictly controlled, with the heating temperature, cooling method, cooling substance and cooling speed. Its typical heating range is between 815 and 900 degrees Celsius, with extra care being taken to keeping the temperature as stable as possible. Quenched and Tempered Steel Plate becomes less brittle and more ductile without sacrificing too much hardness. It is the combination two processes that make it harder, tough and more weldable and ductile than ordinary carbon steel plate. While it takes longer duration to design, the increased strength covers up for the delay. If it becomes too hard after quenching, it can be tempered. The amount of time it is tempered is the determining factor to how much hardness is removed.
A514 Steel Plate is also known as A514 T1 Steel Plate. It is a popular quenched and tempered grade that offers high strength, weldability and machinability. Due to these properties it is typically used in applications where wear resistance and the ability to withstand high impact are important. It is heat-treated through quenching and tempering, a two-step heat treatment process that alters the grain structure of the material to increase strength, hardness and toughness. It is available in eight grades, i.e. Gr A, Gr B, Gr E, Gr F, Gr H, Gr P, Gr Q, and Gr S. ASTM A710 Carbon Steel Plate is high-yield steel grade plate that goes through age hardening to increase its yield and tensile strength. It is available in two specifications i.e. ASTM A710 Gr A (Class 1, Class 2, and Class 3) and ASTM A710 Gr B (Class 1, Class 2, and Class 3). Its applications include the manufacturing of construction equipment, jack-up rigs, truck frames, rail cars, piping components and shipbuilding.
