A liner material for a backing steel cylinder, comprising an iron-based hard facing alloy comprising at least one rare earth element, and a high pressure cylinder assembly, comprising a backing steel cylinder, and a liner covering at least a portion of an inner surface of the backing steel cylinder, the liner comprising an iron-based hard facing alloy comprising at least a rare earth element are disclosed. The thickness of the liner material in the cylinder ranges from 0.030 inches (762 microns) to 0.375 inches (9525 microns). A method of lining a high pressure cylinder assembly, comprising applying an iron-based hard facing alloy comprising at least one rare earth element onto the backing steel cylinder of the high pressure cylinder assembly is also disclosed. The rare earth element includes cerium in an amount less than 2 weight percent based on the weight of the iron-based hard facing alloy.
