​Natrona Heights, Pennsylvania — A western Pennsylvania company says technology at its new mill processes steel up to 20 percent faster than conventional means.
The $1.2 billion Allegheny Technologies facility about 19 miles north of Pittsburgh replaces a plant that opened more than 50 years ago.
The company's president of flat rolled products says the mill is the most expensive investment in its history.
Robert Wetherbee says the state-of-the-art steel mill represents Allegheny's commitment to the area and allows the company to better compete with other national and international steel producers.
The company has seven manufacturing facilities in the region and employs about 2,500 people. It says the new mill could produce at least $100 million in new cost savings this year.
