Braeburn Alloy Steel, Braeburn Road at Allegheny River, Lower Burrell, Westmoreland County, PA

Significance: For much of its history Braeburn successfully maintained its share of the specialty steel market without expensive retooling and large outlays of capital for equipment. Much of the original equipment survives at Braeburn, including two Heroult furnaces which date from 1915 and are among the earliest electric-arc furnaces in existence in the United States.
