Ductile Iron (Nodular Iron)
Strong and Break Resistant
Ductile Iron piston rings and seals can withstand a lot of bending and are very resistant to breaking. Ductile Iron piston rings and seals are roughly twice as strong as Gray Cast Iron piston rings & seals.
Benefits
- Can Withstand Heavy Pounding
- High Bending Strength
- Very Resistant to Breaking
- Able to Withstand High RPMs
- Able to Withstand High Stress
- Roughly 2x Stronger than Gray Cast Iron
Properties
- Microstructure contains rounded (or nodular) shaped grains.
- Does not have the microstructure matrix of Grover’s piston ring iron GC-211 and will induce higher wear on the bore.
Options
Ductile Iron Grades that Meet ASTM A 536:
- 60-40-18
- 65-45-12
- 80-55-06
- 100-70-03
- 120-90-02
