THE EFFECTS OF TEMPERED NONMARTENSITIC PRODUCTS ON THE NOTCH TOUGHNESS AND MECHANICAL PROPERTIES OF AN HY-80 STEEL

Abstract

This report discusses the effects of nonmartensitic products and mechanical properties on the nil-ductilitytransition (NDT) temperature and transverse Charpy V-notch absorption level, for a selected HY-80 steel. Proeutectoid ferrite was found to have the most detrimental effect on the transverse Charpy maximum energy level. Large prior austenitic grain size, irrespective of microstructure, increases the NDT temperature by approximately 100 F. It is recommended that the present HY-80 specification be amended to require two chemistry ranges, one for thin and one for thick plates.
