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

Yield Strength: 100,000 psi
Hardness: Rockwell C26 (Hard)
Heat Treatable: No

The same steel used in automobile bodies, this AHSS (advanced 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. It's sometimes called HSLA (high-strength low-alloy) steel.

Easy-to-Weld A572 Alloy Steel Sheets and Bars

Yield Strength: 50,000 psi
Hardness: Rockwell B75 (Medium)
Maximum Hardness After Heat Treatment: Not Rated
Specifications Met: ASTM A572

Combining strength with weldability and formability, A572 alloy steel is an economical choice for structural components, such as channels, beams, and framing. It has a low carbon content, making it easy to weld with a variety of welding methods. Stronger than other low-carbon steels, such as A36 steel, it handles heavy loads without fracturing. Tested using ASTM A572, these sheets and bars are safe for jobs that require a yield strength of 50,000 psi or less.

Corrosion-Resistant A588 Alloy Steel

Yield Strength: 50,000 psi
Hardness: Not Rated
Heat Treatable: Yes
Specifications Met: See table

Also known as weathering steel, this high-strength steel develops a thin layer of rust over time in outdoor environments that protects the inner steel from corrosion. It’s commonly used in bridges, buildings, and fencing. Since it doesn’t require paint for corrosion resistance, this steel is lower maintenance for outdoor use than other steels. With a yield strength of 50,000 psi, it’s stronger than common low-carbon steels such as A36. Steel meets ASTM standards for corrosion resistance and strength.
