Ductile iron has good corrosion resistance and can be used in seawater environment.
1. Characteristics of ductile iron
Ductile iron is a metal material with medium strength and hardness, and has excellent mechanical properties. The strength of ductile iron mainly comes from the spheroidized graphite particles, which can absorb energy when subjected to stress to prevent crack propagation.
2. Corrosion resistance of ductile iron
Ductile iron has good corrosion resistance because of its dense oxide film on its surface. In addition, ductile iron can also maintain excellent corrosion resistance under high temperature conditions.
3. Use of ductile iron in seawater environment
Ductile iron is widely used in seawater environments, such as saltwater treatment, offshore engine rooms, ship equipment, etc. The good corrosion resistance of ductile iron makes it very reliable for use in seawater environments. Of course, attention should still be paid to the maintenance and care of the material during use to extend its service life. |
