An investigation was made of influence of Cu addition up to 6% on some properties of SUS304L type stainless steel powders manufactured by the water-atomization. The results were as follows:(1) Cu addition decreased ferrite content of atomized powders, lowering particle hardness and also decreased particle hardness and also decreased martensite content induced by compacting. As the result Cu addition improved compressibility and compactibility of powders. 1% Cu addition was equivalent to 0.37% Ni addition for compressibility of powders.(2) Cu addition improved tensile strength and impact value of sintered compacts, when Ni content was 10.5%.The tensile strength of lower Ni equivalent sintered compacts became higher in proportion to the amount of α-phase.(3) Cu addition improved cold formability of sintered compacts. 1% Cu addition was equivalent to 0.35% Ni addition for cold formability. The effect of Cu addition on cold formability was almost equal to that on compressibility of powders under the same influence of plastic deformation.(4) Cu addition improved the corrosion resistance of sintered compacts in boiling 5% H2SO4 solution.
