1/2" X 3" X 12" 4140 CF Annealed Alloy Steel Flat Bar - Made In USA

Got a project that needs some serious muscle?

This is a piece of high-quality 4140 alloy steel.

It's a flat bar, measuring 1/2 inch thick, 3 inches wide, and 12 inches long.

The 'CF' stands for cold finished, which gives it a nice, precise surface and tight tolerances.

Plus, it's in the annealed condition, so it's softer and easier for you to machine, drill, or weld before heat treating.

This steel is made right here in the USA and is traceable to the mill.

If you need certification, just ask.

It's the real deal—domestic, DFARS-compliant material.

Whether you're making a tool, a custom part, or a repair piece, this 4140 flat bar is a solid, reliable choice.

It's new and ready for your workshop.
