Stainless Steel PipeDue to its high thermal resistance, corrosion resistance, and excellent ductility, stainless steel is widely used in various automotive parts such as body panels, chassis, and exhaust systems. Data shows that the usage of stainless steel materials in the automotive industry has been on the rise in recent years. Stainless steel materials are increasingly being applied to decorative components, thanks to their attractive appearance and widespread use.;Compared to other components, materials for the exhaust system place greater emphasis on performance. This discussion outlines the composition and material properties of the exhaust system, explores the corrosion characteristics of materials used in the exhaust system, and explains the current state of materials for each component of the exhaust system.
