Usibor® and Ductibor®

Usibor® and Ductibor® – high resistance boron microalloyed aluminium-silicon (Alusi® coating) steel developed and patented by ArcelorMittal especially for the automotive industry.

This product is part of a group of innovative solutions in steel called S-in Motion developed by ArcelorMittal which allow car manufacturers to make cars up to 20% lighter and reduce CO2 emissions in 15% in car manufacturing and life span. This line of products meets world market trends and the new Brazilian automotive regulations – Inovar Auto – which establishes targets for car manufacturers to develop lighter, safer and more environmentally sustainable cars.

Usibor® 1500 P was especially developed by ArcelorMittal for hot stamping and it is mainly used in the production of structural parts critical for car safety such as A and B columns, reinforcement elements (front and back bumpers, roof and girder beams), and floor plate tunnel.

Ductibor® 500 P is used together with Usibor® 1500 P. The use of both products gives more precision to part forming control for specific car parts and increases the possibilities to uses hot stamped steel in the manufacturing of parts which need high energy absorption.
