Frequently Asked Questions

What is normalizing heat treatment and why is it important for defense forgings?

Normalizing is a heat treatment process where a forged component is heated above its upper critical temperature and then air-cooled at room temperature. The forging process creates uneven grain growth and internal stresses; normalizing breaks up these irregular structures to produce a refined, uniform microstructure with improved tensile strength, toughness, ductility, and machinability—properties that are mandatory in defense-grade components.
