Q. Corrosive properties of caustic?

Sodium hydroxide, more commonly known as Caustic Soda or simply ‘Caustic', is widely used in the petrochemical industry to neutralize acidic process streams. Caustic, under ambient conditions, is typically not particularly corrosive and can be handled in carbon steel or stainless steel equipment. Where product contamination is a concern, stainless steel, nickel alloys or lined carbon steel is often used.
