Factors Affecting the Mechanical Performance of High Manganese Austenitic Steel

High manganese austenitic steel has attracted increasing attention for its application in liquefied natural gas storage tank materials due to excellent ductility and low cost. This paper presents an overview of the research progress high recent years. As a structural material used at temperature environment, should not only have certain strength, but also good toughness prevent brittle fracture temperature. In this work, factors affecting mechanical properties are discussed, possible reasons deterioration low-temperature analyzed, strengthening toughening mechanisms elaborated, which may be beneficial improve steel.
