Main Fields of Application of Alloy C-276
Alloy C-276 is often used in the chemical and petrochemical industries. The material is preferably used in cases where hot contaminated mineral acids, solutions, and organic acids (such as acetic and formic acid) and seawater occur. Other areas of application include the following:
- Sulfuric acid cooler
- Pulp and paper industry, for example for pulping and bleaching vessels
- Equipment and components for sour gas
- Washer and particular retrieval heater and fans for continuous wet combustion and flue gas and desulfurization
- Reactors for the production of acetic acid
- Production and processing technology of contaminated phosphoric acid
