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.
