METHOD OF MANUFACTURING NITRIDED PARTS FROM LOW-CARBON MARTENSITIC STEELS Russian patent published in 1999 - IPC

Abstract RU 2133299 C1

FIELD: metallurgy. SUBSTANCE: consists in plastic working of blank from low-carbon martensitic steel combined with blank hardening and subsequent cooling in air directly from temperature of hot plastic working. Then blank is subjected to nitriding at temperature excluding recrystallization of blank structure with direction of diffusion flow square to direction of deformation. EFFECT: accelerated process of diffusion saturation of blank surface layers. 3 cl, 3 tbl
