Charpy V-Notch Impact Studies on Stress-Relieved HY130 Weldments.

Abstract

A Charpy V-notch impact testing study has been conducted on samples of HY130 steel (ESR and AMVD) and its weldments (MIL 140S MIG, and E12018 and E14018 stick). The parent materials and MIG weldments do not suffer from an appreciable decrease in impact strength when subjected to stress-relief heat treatment followed by air cooling or furnace cooling. E14018 weldments suffer significantly when furnace cooled but not when air cooled from the stress-relief heat-treating temperatures. (Author)
