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

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.
