Abstract NSSMC-NAR-SN-1, SN-3, and SN-5 are austenitic stainless steels with corrosion resistance to nitric acid. The alloys can be abbreviated as NSSMC-NAR-SN-1: LC-17Cr-14Ni-4Si, NSSMC-NAR-SN-3: LC-11Cr-17Ni-6Si-Zr-Ti, and NSSMC-NAR-SN-5: LC-27Cr- 8Ni-Si-N. This datasheet provides information on composition, hardness, and tensile properties. It also includes information on corrosion resistance as well as forming. Filing Code: SS-1237. Producer or source: Nippon Steel and Sumitomo Metal Corporation.

Abstract SO3-Ph-BTBP is a hydrophilic tetra-N-dentate ligand proposed for An(III)/Ln(III) separation by solvent extraction, and a candidate for use in future advanced reprocessing schemes such as GANEX and SANEX. We present the first study of the effect of SO3-Ph-BTBP on the corrosion behavior of stainless steels. Specifically, studies have been performed using steels and conditions equivalent to those found in relevant nuclear reprocessing flow sheets. SO3-Ph-BTBP has been shown to have little effect on either steel passivation or reductive dissolution. However, if driven cathodically into a region of hydrogen evolution at the electrode surface or conversely anodically into a region of transpassive dissolution, observed currents are reduced in the presence of SO3-Ph-BTBP, suggesting corrosion inhibition of the steel potentially through weak absorption of a SO3-Ph-BTBP layer at the metal-solution interface. The lack of any observed corrosion acceleration via complexation of Fe3+ is surprising and has been suggested to be due to the slow extraction kinetics of SO3-Ph-BTBP as a result of a requirement for a trans- to cis-conformational change before binding.
