Interstitially strengthened high carbon and high nitrogen austenitic alloys, oilfield apparatus comprising same, and methods of making and using same
Abstract:
Novel carbon-plus-nitrogen corrosion-resistant ferrous and austenitic alloys, apparatus incorporating an inventive alloy, and methods of making and using the apparatus are described. The corrosion-resistant ferrous and austenitic alloys comprise no greater than about 4 wt. % nickel, are characterized by a strength greater than about 700 MPa (100 ksi), and, when being essentially free of molybdenum (
