Since austenitic stainless steels are susceptible to pitting and intergranular corrosion in the presence of chloride ions, other materials were examined for caustic service [43-47]. These include Fe-Cr alloys, which are resistant to SCC. However, these alloys are brittle and suffer from 475°C embrittlement and sigma embrittlement. A popular alloy that was examined for the caustic evaporator service was E-Brite-26-1, containing 26% Fe and 1 % Mo, which exhibited performance characteristics comparable to that of...

There are several candidate metaUic materials proposed as follows [4, 5] Ni-Cr alloy, Fe-Cr alloy, and Cr-based alloys. Traditionally, Ni-Cr alloys are high temperature resistant materials, such as Incoimel, Hastelloy, and Haynes. Fe-Cr (ferritic) alloys are often used as high temperature metallic components, such as stainless steel (SUS), E-Brite, ZMG-series, and Crofer-series. Cr-based alloys are specially developed for SOFC intercoimects, which contains oxide materials, such as Cr-Fe-Y203.

The first significant alloy developed commercially to meet these requirements contained 26% chromium and 1% molybdenum. To obtain the desired corrosion resistance and acceptable fabrication characteristics, the material had to have very low interstitial element contents. To achieve these levels, the material was electron-beam rerefined imder a vacuum. It was known as E-Brite alloy. Carbon plus nitrogen contents were maintained at levels below 0.02%. 

This alloy is manufactured under the trade name of E-Brite by Allegheny Ludlum Industries, Inc. It is a high-chromium alloy. Refer to Table 8.1 for the chemical composition. Compared to the 300 series of stainless steel, alloy S44627 has a high thermal conductivity and a low coefficient of thermal expansion.
