Corrosion Rates: 316l_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 | concentration pct (%) | 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) |
