Abstract
It is shown that alloying of low-carbon weld metal with manganese leads to formation of a small amount of pearlite and up to 40-50 vol.% of acicular ferrite in it. Owing to a high acicular ferrite content, weld metal of the Fe-Mn-Mo-Ni alloying system is characterised by a higher level of mechanical properties than weld metal of the Fe-C-Mn alloying system
Keywords: low-alloy steels, alloying elements, structural components, поп-metallic inclusions, carbon equivalent
