The purpose of this study is to investigate the effect of fabrication conditions on tensile and impact properties of the sintered SUS304L stainless steel compacts made by powder injection molding. The specimen were made of water-atomized and gas-atomized powders which were blended with a polyamide binder system. The compacts were debound in air at various temperatures and sintered in vacuum at 1573 K, 1623 K and 1673 K for 7.2 ks The density and mechanical properties of the sintered compacts were influenced by debinding temperature. The impact value of the sintered compacts increased lineally with increasing density. The powder characteristics influenced significantly on density, microstructure and mechanical properties of the sintered compacts.
