EFFECT OF AUSTENITIC GRAIN SIZE ON THE PHASE TRANSFORMATION OF A NOVEL 6.5% Cr STEEL FOR FORGED COMPONENTS

In this paper the effect of quenching and tempering (Q&T) thermal treatment on mechanical properties a novel 6.5% Cr steel for forged components is studied. The main innovation in increased hardenability following higher content with respect to more common 5% allowing lower other chemical elements aimed achieve target properties. Following high intrinsic such based poor prior austenite grain size should be expected after quenching. Aim work evaluate analyse dependence it.
