ステンレス鋼粉末の試作研究

抄録

The recent powder metallurgy, especially the demand for sintered products of iron and alloy steels is rapidly increasing and it has also been magnified into the field of high alloy steels together with the tendency of higher density and bigger size.
In order to cope with such situation we decided to push the mass production of powder of raw material and a study was made about powder manufacturing conditions such as water jetting, atomizing of melt etc. after trial installation of powder manufacturing apparatus by means of atomizing method.
Furthermore, researching was done about the influence of atomizing conditions upon characteristics especially about stainless steel powder among high alloy steels. After the results we finally could establish a industrial technique by which we are able to manufacture stainless steel powders for sintered products with stability.
