SA533GrB is an introduction to the steel plate used in pressure vessels in the American standard
SA533GrB is a boiler and pressure vessel steel plate that complies with ASME SA387/SA387M standards. It is mainly used for the manufacture of spherical storage tanks of more than 50 cubic meters, and can also be used for the manufacture of single-layer coil-welded containers, multi-layer hot-sleeved coil-welded containers, multi-layer wrapping containers and other second- and third-class containers and low-temperature pressure vessels. It is widely used in petroleum, chemical industry, power station, boiler and other industries, and is used to make reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, liquefied gas tanks, boiler steam drums, liquefied petroleum cylinders, high-pressure water pipes for hydropower stations, hydro turbine volutes and other equipment and components.

Note:
(1): In order to improve the properties of steel, other trace alloying elements other than the above table can be added, and the data comes from the network and is for reference only.
(2): The allowable deviation of the chemical composition of the finished steel plate should comply with the provisions
of GB/T222 Analysis of the delivery status of SA533GrBCL1 steel plate: SA533GrBCL1 delivery status:
quenching and tempering quenching and tempering state delivery. Of course, technical requirements such as flaw detection standards, flaw detection grades, Z-direction performance, and the addition of special alloying elements can also be added according to the needs, but they need to be agreed upon after communication between the supply and demand parties, and they need to be reflected in the contract.
SA533GrBCL1 steel plate heat treatment requirements
: SA533GrBCL1 steel plate should be heat treated, heated to a suitable temperature in the range of 1550-1800 °F (845-980 °C), the holding time is enough to make the temperature uniform on the entire plate thickness, and then quenched in water. This is followed by tempering 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.
