Technology Description:

The team led by Oak Ridge National Laboratory (ORNL) will develop new cast alumina-forming austenitic alloys (AFAs), along with associated casting and welding processes for component fabrication. ORNL and its partners will prototype industrial components with at least twice the oxidation resistance compared to current cast chromia-forming steel and test it in an industrial environment. These innovations could allow various industrial and chemical processing systems and gas turbines to operate at higher temperatures to improve efficiencies and reduce downtimes, thus providing cost and energy reductions for a wide range of energy-intensive applications.

Potential Impact:

If successful, ORNL's new cast alumina-forming alloys could provide a more energy-efficient effective alternative to chromia-scale alloys.

Security:

If successful, ORNL’s technology will ensure better chemical safety by advancing corrosion-resistant technologies. ORNL technologies would also allow corrosion resistant alloy production using more domestically available resources, by reducing the use of chromium, which is most commonly imported.

Environment:

This technology will greatly improve the efficiency of chemical processing systems and gas turbines, ultimately increasing efficiency for a wide range of energy-intensive applications, such as in heat exchangers.

Economy:

This technology will enable production of longer lasting cast industrial components that will reduce costs and improve productivity by reducing down-time to replace worn components in many different energy production and chemical process applications.
