  • Nodular Iron an overview | ScienceDirect Topics

    Nodular iron is an excellent engineering material, but homogeneity of the material throughout the casting can sometimes be a problem Thus the yield strength may not be as high as anticipated API 618 calls for specimen testing and other NDE in an effort to ensure the quality of nodular iron castings 986 Compressor valves Valve materials are selected for both durability (longtermSelection of riser modulus and shape of nodular cast iron The feeding riser must be large enough to supply additional liquid metal during liquid shrinkage until the temperature drops below the solid phase line and the parts begin to solidify In the same way, the modulus can be used to evaluate the shrinkage of riser, MC is the modulus of casting, MF is the modulus of riser, KM is a constantSelection of riser modulus and shape of nodular cast ironNodular cast iron is a material that has found a increasing number of applications in the automotive industry during the last decade It has a static strength comparable to cast steels and a greater fatigue strength and ductility than grey irons Castability and machinability is good, and all these properties makes it an economic alternative for medium stressed components and for safetyNodular Cast Iron an overview | ScienceDirect Topics
