Frequently Asked Questions

What is closed die forged steel?

Closed die forged steel is steel that has been shaped by compressing a heated billet between two matched dies that completely enclose the material. This process forces the steel into the precise shape of the die cavity, producing components with superior grain flow, high strength, and dimensional accuracy compared to cast or machined-from-bar alternatives—making it ideal for demanding aerospace, defense, and industrial applications.
