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.

Hard Wear-Resistant 52100 Alloy Steel Tubes

Yield Strength: See table
Hardness: See table
Heat Treatable: Yes
Maximum Hardness After Heat Treatment: Rockwell C60
Specifications Met: ASTM A295

Easier to machine than 52100 alloy steel rods, these extremely hard and wear-resistant tubes are often used to create bearings, bushings, and other cylindrical parts that are under constant stress. They’re also known as chrome steel.
