- Annual quantity of 25 to 15,000 pieces
Forging is the application of thermal and mechanical energy to steel bars, billets, and ingots to cause the material to change shape while in the solid-state. This is a different process than casting, by which
metal is melted and poured into a mold in the liquid or molten state. Forging offers uniformity of composition and structure. Steel forgings have minimum variation in machinability and mechanical properties. Forging strengthens the resulting steel product, particularly in terms of impact toughness.
