Performance of Stainless Steel P/M Materials in Elevated Temperature Applications

The performance of stainless steel(SS) powder metallurgy (P/M) materials in elevated temperature applications has become a subject of interest with P/M now being considered for automotive exhaust type applications. This study will outline the results of an investigation into the properties of several P/M stainless steel materials at elevated temperatures and relate these P/M materials to ingot metallurgy counterparts. Recommendations on the manufacturing of stainless steel P/M exhaust system components will also be presented.
