Exhaust Manifold 용 오스테나이트계 스테인리스 강의 고온 변형특성
HIGH TEMPERATURE DEFORMATION BEHAVIOR OF AUSTENITIC STAINLESS STEELS FOR EXHAUST MANIFOLD
초록
Domestic automobile industries have been focusing their effort on development of exhaust manifolds using high temperature stainless steel. Exhaust manifolds fabricated with stainless steels can be categorized into tubular and cast ones. The former is usually manufactured by forming and welding process and the latter by vacuum casting process. In the present study, high temperature mechanical properties of 5 austenitic stainless steels, one was sand cast and the others vacuum cast, were investigated by performing a series of high temperature tensile tests and high temperature low cycle fatigue tests.
