DELAYED FAILURE AND NOTCH TENSILE PROPERTIES OF A VACUUM MELTED 4340 STEEL
Technical Report
·
OSTI ID:4300422
The influence of vacuum melting on the notch tensile and delayed failure properties of a 4340 steel was investigated. The notch ductility and the notch tensile strength of the vacuum-melted 4340 steel are greater than those of electric-furnace-melted 4340 steels at the high strength levels. The vacuum- melted 4340 steel at the high strength levels is also less susceptible to delayed failure than the standard melted 4340 steel. (auth)
