【 摘 要 】

The materials for making the construction elements are selected according to the required conditions and the available material properties. In this sense mechanical properties and material behavior of the materials such as 42CrMo4 steel, X46Cr13 steel and X6CrNiTi18-10 steel were investigated. Mechanical properties of the mentioned materials are shown in the form of engineering stress-strain diagrams, creep behavior is presented in the form of creep curves while uniaxial fatigue of these materials are given using life diagrams. These materials differ in chemical composition, their strength properties differ within 20% while their fatigue limits are significantly different.
