Corrosion Rates: carbon_steel
Quantitative corrosion rate data for metals in various environments — corrosion rate in mm/yr and mpy, pitting potential, crevice and stress corrosion risk ratings, and PREN values
| metal id | environment id | corrosion rate mm yr (mm/yr) | corrosion rate mpy (mpy) | crevice corrosion risk | environment description | metal name | notes | resistance rating | stress corrosion risk | temperature C (C) |
|---|---|---|---|---|---|---|---|---|---|---|
| carbon_steel | atmosphere_industrial | 0.07 | 2.8 | low | Industrial atmosphere (urban/SO2) | Carbon Steel A36/A516 | Industrial atmosphere with SO2; typical 0.03-0.12 mm/yr; depends on SO2 concentration | fair | low | 25 |
| carbon_steel | atmosphere_marine | 0.1 | 3.9 | low | Marine atmosphere (coastal) | Carbon Steel A36/A516 | Atmospheric marine corrosion; sea spray deposition; typical 0.08-0.12 mm/yr in marine coastal zone | fair | low | 25 |
| carbon_steel | co2_wet | 0.5 | 19.7 | moderate | Wet CO2 (sweet corrosion) 25°C | Carbon Steel A36/A516 | CO2 + H2O forms carbonic acid (pH~4); corrosion rate highly dependent on flow velocity and CO2 partial pressure | poor | low | 25 |
