Frequently Asked Questions

Which is better, forged steel or cast steel?

Forged steel is generally superior to cast steel in structural applications. The forging process aligns the metal's grain structure directionally, producing higher tensile strength, fatigue resistance, and impact toughness. Cast steel can contain porosity and inconsistent grain structure. For critical applications in aerospace, defense, or power generation — where part failure is not an option — forged steel is the preferred choice.
