Summary of the lecture
This publication provides a comprehensive guide to selecting nickel-containing alloys for use in caustic soda (sodium hydroxide) environments. It explains the chemical behavior of caustic soda, key corrosion mechanisms, and the performance of various materials—including carbon steel, stainless steels, nickel alloys, duplex alloys, and copper alloys—under different concentrations, temperatures, and contamination conditions. The document also outlines alloy selection for caustic soda production processes (diaphragm, membrane, and mercury cell) and for industries that use caustic soda, such as refining, pulp and paper, and chemical manufacturing. Practical recommendations, corrosion data, and case studies help engineers choose suitable materials to ensure safety, durability, and cost-effectiveness.
What you will learn:
- Understand how caustic soda concentration, temperature, and contaminants affect material performance.
- Recognize common corrosion problems in caustic service, including general corrosion, pitting, and stress-corrosion cracking.
- Differentiate between the main alloy families used in caustic environments and their suitability for specific conditions.
- Select appropriate nickel-containing alloys for equipment used in caustic soda production and handling.
- Apply material selection principles to real industrial processes that use caustic soda (refining, pulp and paper, chemical processing).
- Evaluate safety, reliability, and cost factors when choosing materials for caustic service.
