Dear Elshan,
Can you specify, what’s the media. NACE or other corrosion data bases will provide the corrosion rates for carbon and low alloy steels, however media, concentration, temperatures are all essential.
Appreciate your reply.
Thanks

- Copper; <0.005mm/yr per year, maximum pit rate is 0.02mm per year
- Stainless steel; 0.005 mm per year, with no pitting
