Introduction to SA302MGrC steel plate grades

Introduction to SA302MGrC steel plate grades

SA302MGrC, SA302MGrC, and SA302MGrD belong to the American standard steel plates for boiler vessels, which comply with ASME standards. SA302MGrC, SA302MGrC, SA302MGrD steel plates are usually delivered in normalized, tempered, positive+return. It is used to make reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, liquefied steam tanks, nuclear reactor pressure shells, boiler steam drums, liquefied petroleum cylinders, high-pressure water pipes of hydropower stations, water turbine vortex shells and other equipment and components.
