Forging 101: Comparative analysis

Comparative analysis

How open die and rolled ring forging compares to other techniques

When compared to: Machined bar

Open die and rolled ring forged metal parts deliver:

  • Contoured grain flow yielding greater impact and directional strength
  • Cost savings in material and reduction of waste
  • Less machining and longer tool life
  • Broader material options and size ranges

When compared to: Weldments/fabrications

Open die and rolled ring forged metal parts deliver:

  • Superior and more consistent metallurgical properties
  • Reduced labor, rejection and rework/replacement costs
  • Stronger parts due to the elimination of welds
  • Single-piece design and inspection efficiencies
  • Simplified production requirements

When compared to: Castings

Open die and rolled ring forged metal parts deliver:

  • Directional grain flow and superior final part strength
  • Structural integrity and product reliability
  • Reduced process control and inspection requirements

When compared to: Centrifugal castings

Open die and rolled ring forged metal parts deliver:

  • Greater near net part design flexibility reducing machining time
  • Sound, quality, rejection-free parts
  • Cost savings with the elimination of die, mold and setup costs
  • Continuous grain flow for the optimum combination of fatigue strength and toughness

When compared to: Torch cut plate

Open die and rolled ring forged metal parts deliver:

  • Significantly greater size and grade flexibility
  • Elimination of porosity and laminations
  • Reductions in waste and material costs
  • Controlled directional grain flow yielding optimum strength, toughness and fatigue resistance

When compared to: Closed die/impression die forging

Open die and rolled ring forged metal parts deliver:

  • Single and low-volume quantity options
  • Prototypes with comparable properties
  • Near net shapes with short lead times and the elimination of tooling costs
