### **Product Datasheet: Aermet® 100 Bar (UNS K92580)** #### **Round Bar & Flat Bar Specification** --- ### **1. Product Overview** Aermet® 100 is an ultra-high-strength secondary hardening steel supplied in round bar and flat bar forms. This martensitic alloy achieves an exceptional combination of strength, toughness, and stress corrosion cracking resistance through a specialized Ni-Co-Fe chemistry and precise heat treatment. The bar forms provide optimal material utilization for machining critical components in aerospace and defense applications. --- ### **2.
