A process is disclosed for producing sintered parts from a molybdenum-containing steel alloy atomization, pressing and sintering. The melt used for atomization has a molybdenum content determined as a function of the sintering temperature which lies in a range of 1050 to 1350°C. The carbon content of the powder mixture is no more than 0.05% by weight and the reduction annealing takes place in a temperature range of 850 to 950°C.
L'invention concerne un procédé de production de pièces frittées en un alliage d'acier contenant du molybdène par atomisation, compression et frittage.
