Investigation of Structure and Performance of SAE4330 Steel

Abstract:

Many important heavy forgings used in petroleum machinery field are made of SAE4330 steel. However, the mechanical properties of SAE4330 steel are greatly affected by its microstructures. In this paper, the eliminating methods of grain inheritance and grain boundary inheritance of SAE4330 steel are investigated. The microstructures, tensile properties and impact toughness of SAE4330 steel have been examined. The results show that the grain boundary inheritance is more seriously than the grain inheritance of SAE4330 steel. By using an appropriate heat treatment, the austenite size can be refined from grade zone to grade six. And the Austenite grain boundary inheritance can be removed completely by large deformation and heat treatment. There are three important steps should be strictly controlled for eliminating the mixed structure and coarse-grain of SAE4330 steel.
