  • Caluclating Forging Reductions Forging

    A: Forging reduction is generally considered to be the amount of cross-sectional reduction taking place during drawing out of a bar or billet. The original cross-section divided by the final cross-section is the forging ratio (say 3:1). There is an equivalent reduction on upsetting for forgings being upset during forging (gear blanks, for example).
