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
