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

About Selecting Thermal Insulation

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.

Ground sheets are decarb-free for a uniform surface that will consistently accept heat treating.

Steel that meets ASTM A109 or A36 complies with standards for materials.

Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY after your order ships.

Zinc-Galvanized Low-Carbon Steel Sheets and Bars

These sheets and bars are zinc galvanized for good corrosion resistance. Also known as mild steel, low-carbon steel is easy to machine and form. It's widely fabricated into parts that don’t require high strength, such as enclosures, brackets, and mounting plates. All have been manufactured to meet ASTM A653, ASTM A123, or ASTM A108 standards for quality and performance.

Zinc-coating weight designation indicates the level of corrosion resistance. A higher number means there’s a thicker coating and greater corrosion protection.

Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY after your order ships.

Easy-to-Machine Low-Carbon Steel

Yield Strength: Not Rated
Hardness: Not Rated
Heat Treatable: No
Fabrication: Hot Rolled

Sulfur is added to these sheets, which helps them produce smaller chips than other low-carbon steel sheets when they’re machined. Smaller chips mean less clogging and more coolant flow while you cut. You can also cut faster, create smoother finishes, and keep your tools lasting longer. Often used to make molds, these sheets are comparable to Clean-Cut 20. They have been manufactured to meet ASTM A108 standards for quality and performance.
