Dow Jones reported that workers at a steel plant operated by ArcelorMittal's Argentine unit Acindar were expected later Wednesday to end a 24 hour walkout that union leaders announced following an explosion that injured eight steelworkers.

The explosion, at an Acindar plant in the province of Santa Fe, occurred Tuesday during oven maintenance. Union leaders were widely quoted as telling Argentine media that the walkout would end Wednesday afternoon.

Last week, ArcelorMittal announced that it successfully bought back the 35% stake in Acindar that it didn't already own.
