Corrosion Rates: 316_ss
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 | pren | resistance rating | stress corrosion risk | temperature C (C) |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 316_ss | atmosphere_marine | 0.001 | 0.04 | low | Marine atmosphere | AISI 316 Stainless Steel (UNS S31600) | Excellent atmospheric corrosion resistance; Mo prevents pitting from chloride deposits | 24.5 | excellent | low | 25 |
| 316_ss | co2_wet | 0.02 | 0.8 | low | Wet CO2 / carbonic acid | AISI 316 Stainless Steel (UNS S31600) | Mo addition significantly improves resistance to CO2 corrosion vs carbon steel | 24.5 | good | low | 25 |
