P/M stainless steel flanges and sensor bosses meet critical qualification requirements for exhaust applications

摘要

The use of P/M stainless steel components in automotive exhaust systems continues to grow rapidly. These P/M components have met the stringent requirements demanded for these applications which were formerly only provided by wrought materials. These high density components are being required to pass specific qualification tests designed by OEM's and Tier 1's -Galling, Hot Vibration Leak and High Temperature Oxidation/Corrosion Tests. This paper discusses the performance of P/M stainless steel exhaust flanges and HEGO bosses in a number of OEM and Tier 1 specified performance tests.
