Hot Rolled Steel Plate
Hot rolled steel general information
Hot rolled steel is commonly referred to as Hot Rolled Steel. This term is used broadly to describe all grades of carbon and alloy steel that is milled as discreet plate. This includes A36, A572, A516, A514, AR400, AR500, 4140, 4130, 1020 and other common steel plate grades.
Common Uses of Hot Rolled Steel Plate
Common uses of A36: Shim plates, Gusset plates, bridge plates, bearing plates, robot bases, column base plates, press parallels, press platens, tooling plates, machine plates, machine frames and pedestals, steel table tops, base plates, mold & die, machine mounting plates, etc.
