Super-Austenitic and Duplex stainless steels are advanced alloys used for demanding applications in the oil and gas, desalination and hydrometallurgical industries. Baosteel have invested significantly in developing a production capacity to meet China and Australia’s growing need for these strategic materials. To date crack formation in Super-austenitic and gas pore formation in Duplex stainless steels have a substantial negative impact on production output. The project will leverage the unique combination of experimental and computational facilities at UoW with the practical casting expertise at Baosteel to elucidate the underlying cause of defects and hence increase quality by up to 10%.
