Oversized Easy-to-Machine Gray Cast Iron Rods and Discs
- Yield Strength: Not Rated
- Hardness: Rockwell C20 (Hard)
- Heat Treatable: Yes
- Max. Hardness After Heat Treatment: Rockwell C50
- Specifications Met: ASTM A247
An oversized diameter allows for finishing to your exact requirements. 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 used for gears, pulleys, rollers, and bushings.

- 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.

Easy-to-Machine Impact-Resistant Ductile Cast Iron Rods
- Yield Strength: 45,000 psi
- Hardness: Rockwell C10 (Medium)
- Heat Treatable: Yes
- Max. Hardness After Heat Treatment: Rockwell C50
- Specifications Met: ASTM A536
With a high amount of ferrite, these cast iron rods are easier to machine without cracking than other impact-resistant ductile cast iron rods. Use them to create bushings, gears, pulleys, and pistons. These rods are also known as 65-45-12 ductile iron rods. All conduct electricity. They will become magnetic if exposed to a magnetic field. They’re often used to replace low and medium carbon steel rods.
