Abstract

Nitrogen alloyed steel produced by spray compacting contains (in wt.%): 0.8-2.5 C, 0.03-0.75 N, 0.15-1.8 Mn, not more than 1.0 P, not more than 0.03 S, not more than 0.05 S, 5.0-11.5 Cr, 0.5-6.0 Mo, not more than 4.0 V, not more than 4.0 Nb, not more than 3.5 W, not more than 0.005 O2, and optionally further alloying components and a balance of iron and the usual impurities. Independent claims are also included for: (a) a process for the production of the steel comprising spray compacting the steel using nitrogen as the spray gas; heat treating at up to 1150[deg] C; cooling; heating to the austenitic temperature of 1075-1225[deg] C; quenching; and annealing at 150-625[deg] C; and (b) a composite material containing the steel.
