149alloy 625

Alloy 625 is nominally 21.5Cr-9Mo-3.5Nb and small amounts of Al and C. It is used widely in the aerospace, paper, and petrochemical industries because of its excellent balance of strength and corrosion and oxidation resistance. The results for alloy 625 processed by the LENS system are compared to annealed bar in Table 14.2.

Chemical analysis of the alloy 625 processed by Penn State is shown in Table 14.3, for the deposit, Unfortunately, the chemical composition of the powder was not available for comparison.
