Easy-to-Machine Gray Cast Iron Round Tubes
- Yield Strength: Not Rated
- Hardness: Rockwell C20 (Hard)
- Heat Treatable: Yes
- Max. Hardness After Heat Treatment: Rockwell C50
- Fabrication: Cast
- Specifications Met: ASTM A247
Gray cast iron machines faster with less wear on cutting tools than most types of steel. It also absorbs vibration, so finished parts run quieter than those made of steel. It's often fabricated into gears, pulleys, rollers, and bushings. This cast iron can be surface hardened with heat treating for added wear resistance. These tubes have been manufactured to meet ASTM A247 standards for quality and performance.
