SA283GradeA and SA283GrB are American Standard ASTM steel plate grades. SA283GradeA and SA283GradeB implement the ASME standard production, using converter or electric furnace steelmaking, and the production thickness of SA283GradeA and SA283GradeB is between 8mm-400mm.
SA283GradeA steel plate and SA283GradeB steel plate are delivered in a hot-rolled state, or other heat treatments are performed on the steel plate, such as normalizing, normalizing rolling, annealing, etc. SA283GradeA steel plate and SA283GradeB steel plate have good mechanical properties.
SA283GradeA steel plate and SA283GradeB steel plate are often used in construction machinery, mining machinery, forestry machinery, steel structural parts, large building structure welding, SA283GradeA steel plate, SA283GradeB steel plate can also be used for mechanical equipment shells, or for cutting large mechanical equipment parts, etc.
