SA299GrB steel plate for pressure vessels

1. SA299GrB steel plate is a carbon-manganese-silicon steel plate for pressure vessels in the ASME standard. It is a boiler drum steel and is often used in the manufacture of coal-fired generator set boilers and drums. SA299GrB steel plate is killed steel, and should meet the requirements of fine grain size in the A 20/A 20M standard. It is one of the materials for the boiler drum (steam drum) of coal-fired generator sets.

2. Nowadays, SA299 extra-thick plates are mainly used in the heads and shells of 300MW\600MW subcritical boiler drum products.
