Creep Properties of Microalloyed Steels

Paper analyses the properties of microalloyed steels of S315 MC and S460 MC quality and carbon heat resistance steel of St.45.8 quality at higher temperatures in the creep conditions. The higher values of stress-rupture strength of microalloyed steels in the creep conditions (400-500 C), which are comparable to stress-rupture strength of low alloyed steels, are mainly the result of the precipitation hardening.
