Forging is a superior to casting or machining bar stock since the metal’s natural grain flow is made to conform to the shape of the product. Castings have an isotropic grain structure and, for a given part, may be as strong in compression loads, but forgings are superior in tensile and shear loads due to the utilization of the grain flow.
Our forgings are normally made from special bar quality steel. As steel bars are rolled, the grain structure within the steel is forced to flow along the centerline of the bar. When a forging is produced from the bar, this inherent grain flow bends to follow the contour of the forged shape, thus producing a superior part.
Any machined part, whether produced from bars or plate, will by definition cut through part of the grain flow.
The structural reliability of forgings allows designers to trust the material to adhere to the safety factors of the design. It also can provide more uniform response to heat treatment and machining operations.
