Uniaxial Properties versus Temperature, Creep and Impact Energy of an Austenitic Steel

In this paper uniaxial material properties, creep resistance and impact energy of the austenitic heat - resistant steel (1.4841) are experimentally determined and analyzed. Engineering stress-strain diagrams and uniaxial short-time creep curves are examined with computer controlled testing machine. Impact energy has been determined and fracture toughness assessed. Investigated data that are shown in the form of curves related to ultimate tensile strength, yield strength, modulus of elasticity and creep resistance. All of these experimentally obtained results are analyzed and may be used in design process of the structure where considered material is intended to be applied. Based on these results, considered material may be classified as material of high tensile strength (688 MPa / 293 K ; 326 MPa / 923 K) and high yield strength (498 MPa /293 K ; 283 MPa / 923 K) as well as satisfactory creep resistance (temperature / stress strain (%) at 1200 min: 823 K / 167 MPa 0.25 % ; 923 K / 85 MPa 0.2 %).
