Corrosion Protection Selector
Classify the environment to an ISO 12944 corrosivity category, see how fast unprotected steel corrodes there, and get the specification checklist for the durability you need.
Inputs
DIMENSIONS IN mm
- ISO 9223:2012, Corrosivity of atmospheres: classification (Table 2, first-year corrosion rates)
- EN ISO 12944-2:2017, Classification of environments (Table 1 examples; immersion Im1-Im4)
- ISO 9224:2012, Guiding values for long-term corrosion (carbon steel exponent b = 0.523)
