The Effect of Alloy Steel Design and Heat Treatment on the Mechanical Properties of 3 1/4 NiCrMoV Steel,

Abstract

This report describes work carried out to optimise the composition of 3 1/4 NiCrMoV steels through a stoichiometric balance of the carbon content with the carbide-forming elements Cr,Mo and V. Reduction of the carbon content to the stoichiometric level gives a steel having a very high Charpy upper shelf energy, but the grain refining effect of the carbides is lost and the impact transition temperature increases. An optimised steel containing a slight excess of carbon has been developed that gives a better strength/toughness combination than the commercial steel. (Author)
