Bisalloy Steels congratulates the Royal Australian Navy on 125 years of courage, service and excellence.
As the RAN celebrates 125 years of service, Bisalloy Steels recognises a partnership built on the rigorous standards of Australian manufacturing, producing enduring naval capability
Bisalloy’s naval story started in 1989 with the Collins Class submarine build, supplying qualified high-performance steel for Australia’s first locally constructed submarines. More than 8,000 tonnes of Bisalloy steel went into the nation’s six Collins Class vessels, processed and tested in Australia to meet exacting naval requirements and supporting one of the country’s most significant shipbuilding efforts alongside the Australian Submarine Corporation.
Now, that partnership is entering a new chapter. In 2023, Bisalloy was awarded a contract with the Australian Submarine Agency to qualify Australian-made steel for the SSN-AUKUS submarine program. The qualification process involves more than 4,500 tests, reinforcing Bisalloy’s role in strengthening Australia’s sovereign defence supply chain.
From Collins to SSN-AUKUS, the message is clear: when Australia’s Navy relies on capability at sea, it starts with strength made at home.
