Abstract: Effects of alloy elements and techmical parameters of annealing,pressing, sintering etc. on propertites of FJ41O martensinte sintering stainless steel were studied,The stainless steel structural parts were made by sintering at temperatures between 1200-1300℃ in hydrogen and then cooling in water-jacket. It was observed by metallographic examination that martensintic amount of FJ410 sintering material increases with increase of carbon content. But excessive carbon content will decrease corrosion-resistance and sintering propertites of this material. Thus, I^s very important to correctly select carbon content. In this paper, carbon content between 0.1-0.2% is considered suitable.
