Improvement of the Service Properties of the Weld Joint Metal for Transport Nuclear Power Units Manufactured of Heat-Resistant Steel Grades: Part III.

Abstract

The influence of alloying elements, namely, silicon, manganese, nickel, and molybdenum, contained in the welding wire on the mechanical properties of the metal of automatic submerged-arc welding joints has been investigated. It has been established that the required strength and ductility values and the ductile-to-brittle transition temperature of the weld metal both in the as-welded state and upon high-temperature tempering are achieved by using welding wire with a silicon content of ~0.6% and a manganese content of ~1.5%.
