Hot Forging vs Cold Forging

Details	Hot Forged	Cold Forged
Production Cost	Higher per-part cost for small batchese	Lower cost in high-volume production
Grain structure	Recrystallized	Work-hardened
Strength/Hardness	Moderate (less strain hardening; lower hardness)	Very high
Ductility/Toughness	Ductile	Brittle
Processing	Forged above recrystallization temperature	Formed at or near room temperature
Dimensional Accuracy	Often requires finishing	Tight tolerances, excellent surface finish
Material Range	Can forge high-carbon steel and alloys that are hard to form cold	Best for ductile metals
