Ductile iron is often used as an alternative to plain carbon steel because it has similar strengths and excellent machining properties. Many companies have made the switch from steel to ductile iron to reduce costs while maintaining or improving the quality of their machined parts. Dura-Bar Ductile iron offers a number of advantages over steel including:
- Better Machinability
- Reduced Tool Wear
- Chip Control
- Excellent Surface Finish
- Minimal Deburring
The following grades meet ASTM A536 and ASTM A247 Standards:65-45-12, 80-55-06, and 100-70-03.
This is the most machinable grade of Dura-Bar. The ferritic structure provides for excellent machinability with good surface finishes. It has optimal impact strengths and fatigue properties, and comes in a large selection of tubes, solid rounds, rectangles and squares.
Tensile Strength: 65,000 psi
The pearlite in this grade makes it more wear resistant and stronger than a mostly ferritic grade. Machinability, response to heat treat and surface finishes are good. It comes in a large selection of tubes, solid rounds, rectangles and squares.
Tensile Strength: 80,000 psi
This matrix is mostly pearlite, maximizing strength and wear characteristics for non-alloyed irons. It is also more difficult to machine, but the use of this grade may eliminate heat treating. This grade is not stocked in a full range of sizes. Call for availability or a custom run.
Tensile Strength: 100,000 psi
