- Release of harmful pollutants from iron corrosion that contaminates the air
- Costs of repairing or replacing household equipment that fails
- Lose of efficiency
- Contamination of product
- Damage of metallic equipments
- Inability to use metallic materials
- Lose of valuable materials such as blockage of pipes, mechanical damage of underground water pipes
