Corrosion Prediction & Coating Selector

Use this interactive tool to assess corrosion risk for a base metal in a given environment, including galvanic compatibility with contact metals. The app suggests protection strategies, typical coating systems and a qualitative durability band to support material and coating selection.

This tool provides a qualitative indication of corrosion risk for engineering discussion. Always refer to customer specifications, standards and test data for final design decisions.
Corrosion inputs
Step 1
Service Conditions & Materials
Define base metal, environment and galvanic couple.
Base metal *
Select the closest category. For more detail, add notes below.
Additional base metal notes
Contact metals (if any)
Service environment *
Solution exposure *
Solution chemistry (approx.)
Approximate service temperature
°C (leave blank if ambient)
Area ratio (less noble : more noble)
A small area of less noble metal connected to a large area of more noble metal gives the highest galvanic current density and fastest attack.
Additional notes

The calculation is rule-based and approximate. Use it to inform discussion rather than as a guaranteed life prediction.
