An austenitic stainless steel exhibiting a very high work hardening rate, excellent abrasion resistance, high strength along with good ductility, and good hot workability, consists of, in weight percent, from 0.015% to 0.10% carbon, 5.5% to 10.0% manganese, 0.06% maximum phosphorus, 0.06% maximum sulfur, 2.0% maximum silicon, 12.5% to 20.0% chromium, 1.0% to 3.5% nickel, 0.85% maximum copper, 0.15% to 0.30% nitrogen, and balance iron, said steel having an instability factor ranging from 2.5 to 8.5 calculated by the equation: Instability factor=37.2-51.25(%C)- 2.59(%Ni)-1.02(%Mn)-0.47(%Cr)- 34.4(%N)-3(%Cu). The steel has particular utility for mining or material conveyors, automotive underbodies and similar products requiring high wear resistance and reasonable corrosion resistance. |
