3.2 Design Parameters for Forgings

The design parameters for a forging can best be determined by visualizing the component in its working environment. Five parameters should be considered at the outset.

1. Service loads and peak expected loads
2. Service temperatures
3. Corrosion/oxidation environment
4. Interfacing components
5. Accidental and non-quantifiable conditions

Analysis of these parameters will help to:

• Get all of the factors on the table before design begins
• Identify opportunities for product improvement
• Identify opportunities for cost reduction
• Assist in determining
          Whether or not to design for forging
          Which forging process to select
          Which family of forging alloys will best meet the
          product needs
• Determine if there are opportunities for consolidating more than one part into a single forging design.

The design decision will also be affected by the anticipated production quantities.
