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

Low-Carbon Steel Sheets and Bars

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.

Tight-Tolerance Low-Carbon Steel Bars

With a thickness that's precision ground to a tight tolerance, these bars are sometimes called flat stock.

Zinc-Galvanized Low-Carbon Steel Sheets and Bars

These sheets and bars are zinc galvanized for good corrosion resistance.

Low-Carbon Steel Bars with Rounded Edges

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.

High-Temperature Aluminized Low-Carbon Steel Sheets

Coated with an aluminum-silicon alloy, these sheets resist corrosion while withstanding long-term exposure to high temperatures. Use in drying ovens, furnaces, and smokestacks.

Nickel-Coated Low-Carbon Steel Bars

In addition to good corrosion resistance, the nickel coating provides better wear resistance than the zinc-galvanized coating.

Mold- and Mildew-Resistant Low-Carbon Steel Sheets

A silver-filled resin coating on one side of these sheets protects from degradation caused by bacteria and fungi.

Paintable Galvannealed Low-Carbon Steel Sheets

The galvannealed coating allows these steel sheets to be painted without prepping the surface. They're easier to weld and more scratch resistant than zinc-galvanized steel sheets. Use them for outdoor signs, cabinets, and doors.

High-Strength 1045 Carbon Steel Sheets and Bars

Stronger than low-carbon steel with equally good machinability, 1045 carbon steel is widely used for bolts, studs, and shafts.

Wear-Resistant AR400 Carbon Steel

The nickel and molybdenum content gives AR400 carbon steel the ability to resist wear better than all other carbon steel. It's often used as wear strips, liners, and deflector plates.

Ultra-Wear-Resistant AR500 Carbon Steel

Exceptional hardness makes AR500 carbon steel more resistant to wear and impact than other carbon steel.

Ultra-Machinable 12L14 Carbon Steel Bars

The lead additive acts as a lubricant, which allows 12L14 carbon steel to withstand very fast machining. It's used to fabricate a wide variety of machine parts.

Easy-to-Machine 1215 Carbon Steel Bars

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.

Impact-Resistant A516 Carbon Steel

Even in low temperatures, A516 carbon steel resists breaking upon impact. Also known as pressure-vessel-quality (PVQ) steel, it is mostly used for boilers, storage tanks, and pressure vessels.

Ultra-Strength Carbon Steel (UHSS) Sheets

This UHSS (ultra high-strength steel) allows you to fabricate high-strength parts using thinner material than you could with other types of steel. It is formable, weldable, and more economical than alloy steel.

High-Strength 1084 High-Carbon Steel

Easy to forge, grind, and heat treat, these 1084 high-carbon steel bars offer high strength and resist wear and abrasion.

Spring Steel

Wear-Resistant 1095 Spring Steel Sheets and Strips

Also known as blue-tempered steel.

Easy-to-Form Wear-Resistant 1095 Spring Steel Sheets

These sheets have a softened temper, which is also known as annealed, so they can be easily formed into shape and then heat treated for spring properties.

1075 Spring Steel Strips

Also known as scaleless steel.

Easy-to-Form 1075 Spring Steel Sheets

These sheets have a softened temper, which is also known as annealed, so they can be easily formed into shape and then heat treated for spring properties.
