WhatsApp: +86 18838072829A: Forging reduction is generally considered to be the amount of crosssectional reduction taking place during drawing out of a bar or billet. The original crosssection divided by the final crosssection is the forging ratio (say 3:1). There is an equivalent reduction on upsetting for forgings being upset during forging (gear blanks, for example).
