2.Valves and Fittings
-Forged Valves and Fittings: deforming into desired shapes with compressive force, with/without the use of dies (A105, A182, A350)
-Wrought Fittings: formed through forging or shaping operations: hammering, pressing, piercing, extruding, upsetting, rolling, bending, machining or combinations of these operations.
(A234, A403, A420)
-Cast Valves & Fittings: formed through the solidification of molten metal in a mold (A216, A217, A351, A352)
