Abstract
This paper discusses a new gasket technology to address the increasing demands of providing effective sealing solutions for exhaust systems.
Increasingly, effectively sealed joints are required in exhaust systems to meet environmental and emissions regulations and provide accurate engine management data. These hot gas applications are especially difficult to seal. With low load joints, significant flange movement and distortion plus temperatures in excess of 850°C (1550°F), traditional gaskets often do not provide an effective seal, typically degrading or creeping at operating temperatures.
This paper details a solution to these problems by utilizing a new multi-layer metal gasket technology. The solution consists of a portfolio of new high temperature alloys (HTAs). Each HTA has a unique operating range, all of which are beyond the functional temperature of the commonly used 300 series stainless steel. In addition, the HTAs are all coated with a unique high temperature coating.
