AISI 1030 Steel, as rolled Product Information -:- For detailed product information, please contact sales. -: ### **Technical Data Sheet: AISI 1030 Steel - As Rolled Condition** --- #### **1. Material Overview** AISI 1030 as-rolled steel is a medium-carbon, non-alloy steel supplied directly from hot-rolling operations without subsequent heat treatment or cold finishing. This condition represents the most economical form of the material, characterized by a characteristic mill scale surface and mechanical properties developed through controlled rolling and natural cooling. As a widely available general-purpose engineering steel, it offers a balanced combination of strength, toughness, and manufacturability suitable for numerous industrial applications. --- #### **2. Key Characteristics** - **Cost-Effective Production**: Eliminates additional processing costs associated with heat treatment or cold working - **Good Strength-to-Durability Ratio**: Provides adequate mechanical properties for many structural and mechanical applications - **Versatile Fabrication**: Suitable for welding, machining, and forming with proper techniques - **Natural Surface Condition**: Features characteristic blue/black mill scale requiring removal for many finishing operations - **Predictable Properties**: Mechanical characteristics follow established ranges for hot-rolled medium-carbon steels --- #### **3.
