FE-NI BASED ALLOY SOLDER WIRE FOR 800H ALLOY WELDING AND PREPARATION METHOD THEREFOR, AND 800H ALLOY WELDING METHOD
Document Type and Number:
WIPO Patent Application WO/2020/248878
Kind Code:
A1
Abstract:
An Fe-Ni based alloy solder wire for 800H alloy welding, comprising the following chemical components in mass percentage: C 0.05-0.10％, Si≤1.0％, Mn≤1.5％, Ni 29.0-32.0％, Cr 17.0-19.0％, Nb 0.35-0.45％, Mo 1.50-2.50％, Al 2.5-3.0％, N≤0.03％, B≤0.01％, S 0.002-0.008％, and P 0.008-0.009％, the remainder being Fe; the chemical components of the present Fe-Ni based alloy solder wire are rational; after being used for 800H alloy welding, the resulting welding seam has a tensile strength of 557.6 MPa and elongation of 37.5% at room temperature, and a tensile strength of 420MPa and elongation of 17.25% at 650℃. Also provided are a preparation method for the Fe-Ni based alloy solder wire for 800H alloy welding and an 800h alloy welding method.
