- 1018 Carbon Steel Construction
- ASTM A108 Certified
- 63,800 PSI Tensile Strength
- Excellent Machinability
1018 Cold Rolled Steel Flat Bar is a low-carbon steel product known for its excellent case-hardening properties and superior surface finish compared to hot rolled alternatives. The cold drawing process increases its strength and hardness while maintaining tight dimensional accuracy. With a typical tensile strength of 63,800 PSI and yield strength of 53,700 PSI, 1018 offers a good balance of strength, ductility, and toughness.
As a medium-width bar, this 3" x 1/8" flat is perfectly suited for structural bracing, base plates for machinery, wear strips, and machine ways. Its consistent thickness and flatness ensure reliable performance in fabricated assemblies and tooling jigs where precision is a requirement.
