### **Product Datasheet: Aermet® 100 Forgings (UNS K92580)** --- #### **1. Product Overview** Aermet® 100 Forgings represent the premium product form of this ultra-high-strength secondary hardening steel, manufactured through controlled deformation processes to achieve superior mechanical properties and grain structure. The forging process aligns the metallic grain flow with the component contours, resulting in enhanced strength, improved fatigue resistance, and superior structural integrity compared to other manufacturing methods. These forgings are specifically engineered for the most demanding aerospace and defense applications where reliability under extreme loading conditions is critical. --- #### **2.
