Abstract (en)
[origin: EP1538232A1] Austenitic ferrite-free steel alloy contains (in weight %) up to 0.35 carbon, up to 0.75 silicon, 19.0-30.0 manganese, 17.0-24.0 chromium, 1.90- 5.5 molybdenum, up to 2.0 tungsten, up to 15.0 nickel, up to 5.0 cobalt, 0.35- 1.05 nitrogen, up to 0.005 boron, up to 0.30 sulfur, less than 0.5 copper, less than 0.05 aluminum, less than 0.035 phosphorus and a sum of nickel and cobalt of more than 2.50. An independent claim is also included for a process for the production of the austenitic ferrite-free steel alloy. Preferred Features: The steel alloy contains (in weight %) 3.8-9.8 Ni, less than 0.2 Co, 2.5- 4.5 Mo, 20.0-25.5 Mn, 20.0-23.0 Cr, 0.15-0.30 Si and 0.01-0.06 C.
