Abstract:

This report addresses a mechanical property characterization of a split argon-oxygen decarburized AOD heat of 4340 steel which was further processed by vacuum arc remelting VAR and electroslag remelting ESR into 12. 7 cm 5 inch square forgings. Properties examined were hardness, tensile, Charpy V-notch impact, and fracture toughness as a function of tempering temperature over the range of 163 C 325 F to 649 C 1200 F for both the longitudinal and transverse orientations. Microstructural aspects are also addressed.
