DESCRIPTION

3/4″ x 4″ Steel Flat Bar 1018 Cold Finished (CF) is a precision low-carbon steel flat bar designed for machining, structural support, and fabrication applications requiring tight tolerances and a smooth, clean finish. Manufactured from 1018 cold-finished steel, this flat bar offers improved strength, superior dimensional accuracy, and a scale-free surface compared to hot-rolled steel.

The cold finished (CF) process produces sharp edges and consistent sizing, making it ideal for CNC machining and precision fabrication. Its excellent machinability allows for efficient drilling, milling, turning, and forming, making it a preferred material for machinists and industrial applications.

Key Features

  • Made from 1018 cold-finished steel
  • 3/4″ thickness x 4″ width for increased strength and coverage
  • Smooth, clean surface with precise dimensions
  • Excellent machinability for CNC and fabrication
  • Better tolerances and strength than hot-rolled steel

Common Applications

  • CNC machined components
  • Keys, shafts, and precision parts
  • Tooling and fixtures
  • Brackets, supports, and structural elements
  • Industrial and mechanical fabrication

This 1018 cold-finished steel flat bar is available in multiple lengths with cut-to-size options, allowing you to order exactly what your project requires.

* Prices subject to change without notice due to the Metals Market fluctuations. | All ‘value length’ and ‘value pack’ item measurements are subject to a “mill tolerance”. | A product may be produced several thousandths of an inch, either over or under the stated thickness, and still be within “mill tolerance”. Since we cut the material specifically for your order, they follow these tolerances: Length: +0.125″ / -0.062” – Please note that during cutting, the blade removes about 1/16″ of material (kerf). This is a normal part of the process and is already considered within the stated tolerances.
