摘　　要：According to the requirement of the knowledge of material mechanical properties in structure design procedure,the paper considered experimentally obtained data regarding the high-strength low-alloy A 709 Gr50 steel.In that way,ultimate tensile strength and 0.2 offset yield strength at both lowered and elevated temperatures were presented and analyzed.The effect of temperature exerted on both of the mentioned strengths was presented.Creep responses for selected temperatures and selected stress levels were also considered.All of the tests are related to the uniaxial tensile tests and were performed in the laboratory of the Department for Engineering Mechanics at the Faculty of Engineering Rijeka.According to the requirement of the knowledge of material mechanical properties in structure design procedure,the paper considered experimentally obtained data regarding the high-strength low-alloy A 709 Gr50 steel.In that way,ultimate tensile strength and 0.2 offset yield strength at both lowered and elevated temperatures were presented and analyzed.The effect of temperature exerted on both of the mentioned strengths was presented.Creep responses for selected temperatures and selected stress levels were also considered.All of the tests are related to the uniaxial tensile tests and were performed in the laboratory of the Department for Engineering Mechanics at the Faculty of Engineering Rijeka.
