Presentation transcript:

STEEL AS A CONSTRUCTIONAL MATERIAL Advantages: Combination of high stiffness (E = 2,1∙105 MPa), static (σT) and syclic (σ-1) strength with sufficiently high structures reliability (δ , KCU) in service Wide range of mechanical and service characteristics at the expense of change in composition (alloying) and structure (heat treatment and other technologies) Disadvantages: Large specific weight, low specific strength σT /γ Susceptibility to corrosion

ALLOYED STEELS Alloying elements: increase strength properties of steel, but may reduce an impact toughness (> 1 % alloy additives); elevate the temperatures of phase transformations (critical points of steel); decrease a critical cooling rate of quenching; enlarge hardness penetration; reduce average grain size; add special service properties (heat resistance, corrosion resistance at al.)
