Introduction to SA204 Gr A / B / C steel plate
SA204 American standard vessel plates are divided into three levels: A, B and C. SA204 Gr A, SA204 Gr B and SA204 Gr C are killed steel. SA204 Gr A, SA204 Gr B and SA204 Gr C steel plates are mainly used for welding Mo alloy steel plates of boilers and other pressure vessels.
SA204 Gr A / B / C steel plate executive standard: ASME SA204 / SA204M.
SA204 Gr A / B / C steel plate delivery status: normalized rolling, normalized.
The steel plate can be delivered in normalized condition with the thickness of more than 40mm, and it can also be delivered in normalized condition.
