# Caustic Stress Corrosion Cracking

## Summary

Caustic refers to chemicals that fall in the group of strong alkalis. The most common caustics are sodium hydroxide (NaOH), which is often referred to as caustic soda, and potassium hydroxide (KOH). Some materials of construction are subject to stress corrosion cracking (SCC) when in contact with caustic solutions at elevated temperatures. Materials susceptible to caustic SCC primarily include carbon steels, but low alloy steels and austenitic chromium-nickel stainless steels are known to suffer caustic SCC.
