POWDER OF STAINLESS STEEL Russian patent published in 2009 - IPC B22F1/00 C22C33/02 B22F3/12 

Abstract RU 2345866 C2

FIELD: metallurgy.

SUBSTANCE: stainless steel powder contains at least 10 wt % of chrome. Stainless steel powder contains, wt %: 10-30 chrome, 0.1-1.0 vanadium, 0.5-1.5 silicon, less than 0.1 carbon and less than 0.07 nitrogen. Vanadium presents in amount at least 4 times exceeding summary content of carbon and nitrogen. From composition, containing steel powder and at least one admixture, chosen from group, including lubrication, admixtures for fluidity increasing, improving admixture processibility and alloying elements, by means of pressing and following sintering at 1150-1350°C it is received sintered detail.

EFFECT: reduction of sintering temperature, high density of material.
