초록
In order to study the mechanical properties of high nitoren steel with ageing time, hardness, tensile stress several basic properties of Fe-Mn-Cr-Ni-N steel have been studied. With increasing partial pressure of nitrogen and ageing time to 10h, hardness and tensile stress are increased, but decreased beyond 10h because of over ageing. It is considered that the main factor related with mechnical properties is carbide precipitate,
