The Forging Advantage. . .
Directional Strength: Controlling deformation during the forging process results in improved metallurgical properties.
The forging process produces directional alignment (grain flow) for important directional properties of strength, ductility, and resistance to impact and fatigue.
Impact Strength: Through proper grain flow orientation, the forging process can develop the maximum impact strength and fatigue resistance possible in a metal.
Structural Integrity: As is well known a forging's structural reliability is excelled by no other metalworking process.
There are no internal gas pockets or voids that may cause unexpected failure under conditions of high stress or impact.
This means more realistic safety factors based on material that will respond predictably to its environment without costly special processing to correct internal defects.
Size Range: Forged parts are economically produced in a broad range of sizes and shapes.
Uniformity: The consistency of material and dimensions from one forged part to the next, and from separate production lots of forgings produced months or years apart, is extremely high.
Forgings are made through a carefully controlled sequence of production steps, in contrast to a random flow of material into the desired shapes.
Uniformity in composition and structure, piece to piece, insures reproducible response to heat treatment, minimum variation in machinability, and consistent property levels of finished parts.
Strength-To-Weight Ratio: The higher strength-to-weight ratio can be used to reduce section thickness in part design.
Compatibility: Forging components have superior response to all forms of heat treatment.
Due to the near absence of structural defects, forgings offer the best opportunity for strong, efficient welds.
Due to the lack of internal discontinuities and surface inclusions, forgings provide a dependable machining micro-structure for most metal-cutting processes.
Forged parts can be readily fabricated by welding, bolting, or riveting, and are suited for most surface conditioning.
A forging can also be designed to eliminate multiple assembly components.
Economic Advantages: Forging's superior functional advantages of strength, fatigue resistance, reliability, and high quality combine into economic benefits.
Uniform dimensional relationships result in consistent machinability and predictable response to heat treatment.
This, combined with obvious strength-to-weight ratios, make forgings a top priority of the cost-conscious user.
