- 1018 Steel Construction
- ASTM A108 Certified
- 63,800 PSI Tensile Strength
- Excellent Machinability
1018 Cold Rolled Steel is a low-carbon grade produced through a cold drawing process that increases its strength and hardness while maintaining tight dimensional tolerances. This process results in a smooth, scale-free surface ideal for parts requiring minimal prep before finishing. Conforming to ASTM A108, it provides a balance of strength, ductility, and toughness, with excellent weldability and machinability.
The large 4" width of this bar makes it highly suitable for manufacturing base plates for machinery, heavy structural supports and bracing, wear strips for industrial equipment, and components for dies and fixtures where stability and a flat, true surface are critical.
