Abstract

"This paper describes a new method of making austenitic stainless steel (18/8) powder by electrochemical disintegration. The method used an external direct current applied to a heat-treated stainless steel anode, and a platinum cathode in an electrolyte of an aqueous solution of 20% HNO3 and 1% H2SO4 by weight respectively.

Special attention has been paid to the size distribution of sieve and sub-sieve sizes, and the following ranges were found: approximately one-half lies between the limits of 200 and 325 mesh, and one third is finer than 325 mesh, with the remainder about +200 mesh, average specific surface 209.6 sq. cm/gm. The powder obtained is about 68% of the weight of the working anode.

Chemical analysis of the powder showed 16% reduction of the original carbon content; chromium and nickel were slightly affected. The powder produced is still in the normal range of 18-8 stainless steel"--Abstract, page 5.
