Abstract

This paper deals with effect of long-term exploitation on structure and mechanical and fracture properties of X20CrMoV11-1 grade steel. Mechanical properties were evaluated both using standard test specimens and small punch test (SPT). Obtained results were compared with received state conditions. Creep properties, crack growth rate as well as fracture toughness tests were carried out too.

Keywords: Mechanical properties, X20CrMoV11-1 steel, fracture behavior, crack growth rate, creep properties
