    Abstract

    Selection of metals for gaseous oxygen service requires consideration of compatibility test data and the design of the specific component. Of the various oxygen compatibility tests, the promoted ignition test provides one of the best indications of the performance of a metal in gaseous oxygen. Promoted ignition test results for copper alloys, nickel alloys, and iron alloys are reviewed. The use of the extended fire triangle to predict the performance of a component is discussed. Materials are selected for a hypothetical control valve for 1.7 MPa (250 psi) oxygen service by considering compatibility test data and the valve design.
