A533 GrB CL2 steel is American standard pressure vessel steel plate, which belongs to nuclear power vessel steel plate. The steel is one of the main materials used in the nuclear power industry, and it is widely used in boiling water reactors and pressure reactors.
Standard: ASTM A533/A-533M.
A533 GrB CL2 steel plate heat treatment requirements
A533 GrB CL2 steel plate should be heat treated, heated to a suitable temperature in the range of 1550-1800°F (845-980°C), and the holding time is sufficient to make the temperature uniform across the thickness of the plate, and then quenched in water. Then temper at a suitable temperature to produce the performance required by the standard, but the tempering temperature should not be lower than 1100°F (595°C), and the holding time should be at least 1/2h/in. (1.2min/mm) thickness , But not less than 1/2h.

A533 GrB CL2 steel production process
The smelting method is: the steel should be killed steel and meet the requirements of A 20/A, 20M standard fine austenite grain size.
A533 GrB CL2 steel plate is one of the main materials used in the nuclear power industry. It is often used in the tube section of nuclear reactor vessels, where high-level radiation may affect the performance of steel. The steel plate is widely used to prevent hydrogen embrittlement, hydrogen corrosion, hydrogen peeling, and sulfide corrosion. It also has good low temper embrittlement performance in petroleum, chemical, power station, boiler and other industries. It is used to make reactors, heat exchangers, and separators. , Spherical tanks, oil and gas tanks, liquefied gas tanks, nuclear reactor pressure shells, boiler drums, liquefied petroleum gas cylinders, high-pressure water pipes of hydropower stations, turbine volutes and other equipment and components.
