# High Temperature Organic Acid Corrosion

## Summary

High-temperature organic acid corrosion is a mechanism very similar to naphthenic acid corrosion, caused by direct reaction of steel with organic acids at temperatures well above the aqueous dewpoint; typically in the temperature range from 180°C (355°F) to 400°C (752°C).
