An iron-base, hard facing alloy characterized by the absence of cobalt but having performance characteristics approximating cobalt-base, hard surfacing alloys. The alloys consist essentially of, by weight, from about 3% to about 5% boron, up to about 10% chromium, from about 27% to about 43% nickel, from about 0.1% to about 5% silicon, from about 0.2% to about 1.5% carbon, from about 0.1% to about 2% manganese, with iron comprising the balance.
