Abstract

This research aims at understanding the relationship between powder chemistry, oxide species, sintering atmosphere and sintering response in compaction grade 316L stainless steel.This will lead to development of a process control tool to obtain higher dimensional precision andbroaden the market for P/M stainless steels. Six different lots of 316L stainless steel were compacted, sintered, and measured for dimensional change. Correlation values were drawn between the dimensional change and bulk chemistry, surface chemistry, and particle size. The data indicate a strong influence of surface chromium content, bulk manganese content, bulk carbon content, and D10 particle size on shrinkage.
