Split Heat Mechanical Property Comparison of ESR (Electroslag Remelting) and VAR (Vacuum Arc Remelting) 4340 Steel. Revised

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.
