A625 Alloy

Alloy name: A625
Diagram No.: 1075
Type of diagram: TTT
Chemical composition in weight %: 20.5-22.5% Cr, 4.0-5.0% Fe, 8.1-8.9% Mo, 3.4-3.7% Nb+Ta, 0.01-0.40% C, 0.02-0.10% Mn, 0.05-0.10% Si, 0.02-0.04% Al, 0.1-0.25% Ti, balance is Ni
Alloy group: Nickel-based alloys
Note: Thermal exposures also can markedly change the microstructures of weld metal or castings. Even if care is taken to avoid Laves phase in the ascast structure, the enrichment in Nb in the interdendritic regions will lead to accelerated precipitation reactions upon heating. The Delta often could be seen to be localized in the interdendritic regions of the weld structure. Figure shows the effects of various thermal treatments on the appearance of Delta in this material, versus the T-T-T curve for Delta in wrought material. In this particular weld the time for Delta formation was reduced by a factor of about 50 versus the wrought material.
