Document Type and Number:
WIPO Patent Application WO/2024/069985
Kind Code:
A1
Abstract:
This flux cored wire comprises a steel exterior skin and flux, where the chemical composition of the steel exterior skin is: 0 to 0.650% of C; 0.03-0.50% of Is; 3.1-30.0% of Mn; 0-0.050% of P; 0-0.050% of S; 0-5.0% of Cu; 1.0-30.0% of Ni; 0-10.0% of Cr; 0-10.0% of Mo; 0-1.0% of Nb; 0-1.0% of V; 0-1.0% of Co; 0-1.0% of Pb; 0-1.0% of Sn; 0-0.10% of Al; 0-0.10% of Ti; 0-0.1000% of B; 0-0.500% of N; and the remainder being Fe and impurities. The flux cored wire satisfies Mn + Ni ≥ 5.0% and Mn + Ni + Cr ≥ 15.0%, and the fcc percentage of the steel exterior skin is at least 70%.
