About Carbon Steel, Alloy Steel, Spring Steel, and Cast Iron

Low-Carbon Steel Wire

Also known as black-annealed wire.

Zinc-Galvanized Steel Wire

This wire is zinc galvanized for good corrosion resistance.

PVC-Coated Steel Wire

Coated with PVC for corrosion resistance, this carbon steel wire will stand up to outdoor use.

Low-Carbon Steel Rods and Discs

Also known as mild steel, low-carbon steel is easy to machine, form, and weld. It's widely fabricated into parts that don’t require high strength.

Zinc-Galvanized Low-Carbon Steel Rods

These rods are zinc galvanized for good corrosion resistance.

Tight-Tolerance Low-Carbon Steel Rods

These rods are precision ground and held to a strict straightness tolerance, so they're ready for turning in a lathe.

Easy-to-Machine 1215 Carbon Steel Rods

A lead-free alternative to 12L14, 1215 carbon steel contains the same amount of sulfur and phosphorus for excellent machinability. It is often used for shaft couplings, studs, and pins.

Tight-Tolerance Ultra-Machinable
12L14 Carbon Steel Rods

Ready for turning in a lathe, these rods are precision ground and held to a strict straightness tolerance.

Lubricated 1080 Spring Steel Wire

Also known as music wire.

Lubricated 1065 Spring Steel Wire

This wire is coated with oil for corrosion resistance and lubricity. Use it for bundling and as tag wire.

Lubricated 1065 Spring Steel Wire Assortments

Always have the right size wire on hand with a 72-piece assortment.
