PITTSBURGH, March 01, 2020 (GLOBE NEWSWIRE) -- U. S. Steel has closed on the purchase of POSCO-California Corporation (POSCAL)'s 50% partnership interest in USS-POSCO Industries (UPI), effective February 29, 2020.  After a long, collaborative relationship, U. S. Steel and POSCAL concluded that ownership of UPI by a single group represents the best opportunity for UPI to continue operating effectively and serve its customers.
