Comparison of Some Structural and Stainless Steels Based on the Mechanical Properties and Resistance to Creep
Knowledge of the properties of materials and their behavior in certain environmental conditions is one of the most important factors in the procedure of materials selection. In accordance with this fact, this paper presents and analyzes the experimental results relating to two structural (1.0044, 1.7228) and two stainless steel (1.4305, 1.4122) materials. Stress-strain diagrams as well as creep curves related to short-time creep are presented. According to the mentioned diagrams, the ultimate tensile strength, yield strength and modulus of elasticity are determined. On the other hand, based on material creep curves, some conclusions regarding to creep resistance may be given. Also some data related to Charpy impact energy is shown as well as fracture toughness assessment based on impact energy is made. Based on experimental results it can be said that all of the investigated materials have quite high tensile strength and yield strength. Also, these materials may be treated as creep resistant at temperature of 400 °C if the stress level does not exceed 50 % of the yield strength at this temperature.
