Main fields of application of alloy C276

AlloyC276 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:

- Sulfuric acid cooler

- pulp and paper industry, for example for pulping and bleaching vessel

- Equipment and components for Sour Gas

- Washer and particular retrieval heater and fans for continuous wet combustion - flue gas and desulphurisation

- Reactors for the production of acetic acid

- Production and processing technology contaminated phosphoric acid
