United Steelworkers members at Allegheny Technologies, Inc. have ratified a new, four-year contract. The specialty steelmaker made the announcement Tuesday night. The union, however, did not provide any details on the results of the voting. The deal puts an end to their strike that began March 30 over disagreements on pay and healthcare coverage. The union says workers will receive a raise and their health care was preserved without premiums. They are expected to be back to work by Monday.
