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

Yield Strength: 36,000 psi
Hardness: Not Rated (Medium)
Heat Treatable: See Table
Max. Hardness After Heat Treatment: Not Rated
Specifications Met: See Table

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 these angles can be surface hardened with heat treating.
