Abstract

The present invention relates to a weld metal joint subjected to flux cored arc welding (FCAW) used for weld structures, such as ships, buildings, bridges, marine structures, steel pipes, and line pipes, and a steel member having the weld metal joint, and more particularly, to a flux cored arc weld (FCAW) metal joint having excellent CTOD properties at low temperature and a steel member having the FCAW metal joint. A flux cored arc weld metal joint having excellent CTOD properties at low temperature may include, by weight: 0.01 to 0.2% C, 0.1 to 0.5% Si, 1.0 to 3.0% Mn, 0.5 to 3.0% Ni, 0.01 to 0.1% Ti, 0.0010 to 0.01% B, 0.005 to 0.05% Al, 0.003 to 0.006% N, at most 0.03% P, at most 0.03% S, 0.03 to 0.07% O, the FCAW metal joint satisfying a relation of 0.7≤Ti/O≤1.3, 6≤Ti/N≤12, 7≤O/B≤12, and 1.2≤(Ti+4B)/O≤1.9, and the balance of Fe and unavoidable impurities, the FCAW metal joint including a microstructure having acicular ferrite of 85% or more and at least one of the balance of bainite, grain boundary ferrite, and polygonal ferrite. A steel member includes the metal weld joint. According to the invention, there is provided a flux cored arc weld metal joint having a high- strength property and CTOD properties at low temperatures and a steel member having the metal weld joint.
