SA302 GrB steel plate

SA302 GrB steel plate is widely used in petroleum, chemical industry, power station, boiler, etc., for making reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, liquefied steam tanks, nuclear energy reactor pressure shells, boiler drums, liquefaction equipment and components such as petroleum cylinders, high-pressure water pipes of hydropower stations, and turbine volutes.

Chemical composition of SA302 GrB steel plate:
C: 0.25, Mn: 1.07-1.62, P: 0.035, S: 0.035, Si: 0.13-0.45, Mo: 0.41-0.64

Tensile strength of SA302 GrB steel plate:
Tensile strength, (MPa): 80-100 (550-690)
Yield Strength, min. (MPa): 50(345)
Elongation, %: 18

Heat treatment of SA302 GrB steel plate:
SA302 GrB steel sheets with thickness ≤2in (50mm) are usually heat treated in the as-rolled condition. SA302 GrB plates can also be ordered normalized or stress relieved, or normalized and stress relieved. Thickness > 2in (50mm) steel plate should be normalized. When normalizing steel plates with a thickness of ≥ 4 in (100 mm), the cooling method can be accelerated by blasting or liquid quenching to achieve mechanical properties similar to those produced by normalizing steel plates with smaller thicknesses.

SA302 GrB steel plate is alloy steel suitable for welding boilers and other pressure vessels. Heat treatment: normalizing or controlled rolling.
