What is Ductile Iron?

The tensile strength of cast iron is 20,000 – 60,000 psi while ductile iron starts at 60,000 psi and can go to 120,000 psi. The yield strength for ductile iron is generally 40,000 – 90,000 psi but the yield strength of cast iron is so low it is considered not measurable. Let us put strength in a different way.

Relation between Graphitic Corrosion and Strength ...

 · The corrosion behavior and the degradation of the gray cast-iron pipes, which had been buried for 22 to 79 years and used for natural water, have been investigated. The rate of the graphitic corrosion of pipes was in the range of 0.167 to 0.25mm/yr. The graphitization reduced the real wall thickness so that the strength of pipe was lowered.

Cast Iron

 · Cast iron is extremely resilient to mechanical strain, boasting over ten times the crushing strength, meaning that if a system is struck, hit or crushed accidentally, it is much more likely to survive without damage. Physical strength isn''t its only quality; it is also far more resistant to temperature changes than HDPE systems.
