The effect of heat treatment on the mechanical behavior of a 0,20 % steel with Cr and Mo addition is here reported. Such steel can just target the mechanical properties achievable by its intrinsic hardenability. Aim of this paper is to evaluate the mechanical behavior dependence as a function of different quenching and tempering (Q&T) treatments. Results show that, after Q&T, the material can target a - 20°C fracture appearance transition temperature (50% FATT) measured by a Charpy-V impact test making this steel suitable for low temperature application.

Abstract

The effect of heat treatment on the mechanical behavior of a 0,20 % steel with Cr and Mo addition is here reported. Such steel can just target the mechanical properties achievable by its intrinsic hardenability. Aim of this paper is to evaluate the mechanical behavior dependence as a function of different quenching and tempering (Q&T) treatments. Results show that, after Q&T, the material can target a - 20°C fracture appearance transition temperature (50% FATT) measured by a Charpy-V impact test making this steel suitable for low temperature application.
