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

About Tool Steel

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, such as fixture clamps, mounting plates, and spacers. Some of this material can be surface hardened with heat treating.

Tight-Tolerance Low-Carbon Steel Bars

With a thickness that's precision ground to a tight tolerance, these bars are sometimes called flat stock. Low-carbon steel, also known as mild steel, is easy to machine, form, and weld. It's widely fabricated into parts that don’t require high strength, such as fixture clamps, mounting plates, and spacers. This material can be surface hardened with heat treating.

Shim Stock

Cut it into custom shapes to fit your application.

For accurate leveling, choose materials such as steel or stainless steel, which are hard enough to resist scratching and deforming. Softer shims, like copper or aluminum, can be used as wear plates between components that rub together, preventing damage to equipment. Metal shims include a material certificate with traceable lot number and test report.

Carbon steel shim stock has excellent strength and can be welded, but isn't as corrosion resistant as other shims.
