Requirements for P/M Stainless Steel Materials in Order to Meet Future Exhaust System Performance Criteria
Due to more stringent regulatory restrictions, the requirements for exhaust system components have become more demanding. The flanges, in particular, must provide tight sealing capability, and they must maintain this sealing capability for countless numbers of thermal cycles. The tough creep and oxidation criteria, coupled with the increased corrosion resistance required to meet the long term durability and weld integrity is moving exhaust system components toward Stainless Steel materials. The competitive cost benefits offered by the Powder Metal forming technology for fabricating Stainless steel exhaust system flanges has driven extensive study and testing of a variety of P/M exhaust flange applications.
