ArcelorMittal Dofasco invests in extra capability to produce Alusi®-coated Usibor® Press Hardenable Steel (PHS)

December 2020

ArcelorMittal Dofasco announced a coating addition of its No.5 Hot-Dipped Galvanizing Line in Hamilton (Ontaria, Canada) to Aluminum Silicon (Alusi®) for the production of ArcelorMittal’s patented Usibor® Press Hardenable Steel for automotive structural and safety components. With the investment, ArcelorMittal Dofasco will become the only Canadian producer of Alusi®-coated Usibor®. This investment complements additional strategic North America developments announced previously, including a new Electric Arc Furnace at AM/NS Calvert in the US and a new hot strip mill in Mexico.

The total project cost is $24M CAD and the first  Alusi®-coated Usibor® product is expected to come off the line in H2, 2022. No.5 Line is planned to produce up to 160,000-tons of Alusi®-coated press hardenable steel. 


“The addition of Alusi® Coated Usibor® capacity at ArcelorMittal Dofasco, in addition to our existing line at AM/NS Calvert, provides our valued Automotive customers with improved regional access to advanced high strength steel that is key to meeting the demands of new vehicles for lightweight, yet stronger structural and safety components. This investment further secures ArcelorMittal’s leadership in the North American automotive market. 

Brad Davey, CEO, ArcelorMittal North America


“This latest investment in our Hamilton steelmaking and finishing operations recognizes that automotive manufacturing is focused on environmental performance, with automakers focusing on designing and building vehicles that are lighter, stronger, safer and more sustainable. Since 2013, we have invested more than $800 million CAD in capital projects at ArcelorMittal Dofasco that ultimately enable us to deliver smarter steels to our valued customers.  

Sean Donnelly, CEO, ArcelorMittal Dofasco
