ArcelorMittal North America will invest $18.5 million (CAD $24 million) to add capability to ArcelorMittal Dofasco’s No. 5 Hot-Dipped Galvanizing Line. The investment will allow Dofasco to add Aluminum Silicon (Alusi®) to its patented Usibor® Press Hardenable Steel for use in automotive structural and safety components.
“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,” said Brad Davey, CEO, ArcelorMittal North America.
The first Alusi® Coated Usibor® product is expected to come off the line in the second half of 2022. Up to 160,000 tons of Alusi® coated steel will be produced on the No. 5 line.
The investment is part of a planned revamp of ArcelorMittal’s North American assets that includes a new EAF at AM/NS Calvert in Alabama and a new hot-strip mill in Mexico.
Since 2013, ArcelorMittal has invested more than $622 million at Dofasco including a new galvanizing line (No.6), a new utilities boiler and turbo generator capable of producing 20 megawatts of power on site, the modernization of the hot mill and the digitalization of the ladle metallurgy furnace facility.
