Easy-to-Machine Gray Cast Iron Sheets and Bars
- Yield Strength: Not Rated
- Hardness: Rockwell C20 (Hard)
- Heat Treatable: Yes
- Max. Hardness After Heat Treatment: Rockwell C50
- 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, and bushings.

Impact-Resistant Ductile Cast Iron Bars
- Yield Strength: 55,000psi
- Hardness: Rockwell C20 (Hard)
- Heat Treatable: Yes
- Max. Hardness After Heat Treatment: Rockwell C60
- Specifications Met: ASTM A536
Ductile cast iron is strong, resilient, and able to handle repeated stress without breaking. it also absorbs vibration, so finished parts run quieter than those made of steel.
Certificates with a traceable lot number are available for these products. Download certificates from ACTIVITY after your order ships.
Any-Which-Way Angle Plates
The handle extends the full length and height of these plates for use on any of their six sides. Ensure accurate right angles and hold workpieces and fixtures perpendicular to a machine table by securing them to the plate with clamps.
