Home > Process > Why Forging is better
Forging is a superior to machining bar stock since the metal's natural grain flow is made to conform to the shape of the product. For this reason, forgings are superior in tensile and shear loads.
Our forgings are normally made from special bar quality steel. As steel bars are usually 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. This renders the material more liable to fatigue and more sensitive to stress corrosion cracking.
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.
