Mechanical Properties and Fractography of Electroslag Remelted 300M Steel.

Abstract

Engineering and stress corrosion cracking properties, with microscopic examination of fracture surfaces, are presented for a high strength electroslag remelted 300M steel. Comparisons are made of electroslag remelted 4340 steel and electroslag and vacuum arc remelted 300M and 4340 steels. Electroslag remelted 300M steel at high strength levels can achieve the mechanical property levels obtained by vacuum arc remelting in the longitudinal orientation. However, the short transverse ductility of electroslag remelted 300M steel varies considerably and can be unacceptably low. Scanning electron microscopic examination of short transverse tensile specimens having good ductility did not reveal any fractographic differences that could be related to the heat treatment process. Impact energy varied with orientation. No improvement in stress corrosion cracking susceptibility was obtained over VAR 4340 steel. (Author)
