Abstract：
How to choose the materials according to the working temperature of the exhaust manifold was a concern of the engine designers.The mechanical properties of ductile iron,silicon-molybdenum vermicular iron,silicon-molybdenum ductile iron,high-nickel ductile iron and heat-resistant steel at different temperatures should be measured under production conditions.Materials selection according to the mechanical properties at different temperatures was proposed.But also consider the exhaust manifold was not only the structure,or the bearing parts.Therefore,according to the loading conditions and operating conditions,the structure can be strengthened or materials with better high temperature performance can be selected.
