Abstract：With the polyoxymethylene (POM) as the main components of catalytic debinding binder， the feedstock for 304 stainless steel powder injection molding was prepared. The weight-loss process， debinding process and linear shrinkage ratio were analyzed， and the properties of sintered bars were detected. Results show that the suitable injection temperature is 180-200 ℃， the debinding temperature is below 250 ℃. The average density of injection blank is 5.399 g/cm3， and the average density of sintered samples is 7.829 g/cm3. The linear shrinkage ratio in the direction of length， width and height are 14.11%，14.02% and 14.21%， respectively. The microstructure of the sintered compacts is typical austenite.
