“…In this context, austenitic stainless steels, and specifically, 316L stainless steel, are the most used structural materials in many industries, mainly due to their good corrosion resistance, which is attributed to the addition of Cr and Mo [17][18][19], and their good mechanical properties at high temperatures [20]. Moreover, its good oxidation resistance makes 316L stainless steel an excellent candidate to be used in CSP plants and high-temperature parts such as pipelines or hot tanks manufactured with stainless steel [21][22][23].…”

The effects of different molten salts on the corrosion resistance of laser powder bed fusion (L-PBF) 316L stainless steel was evaluated at 650 and 700 °C. The samples were characterized via XRD and SEM/EDX after high-temperature corrosion tests to evaluate the corrosion damage to the L-PBF 316L stainless steel caused by the molten salts. The presence of the salts accelerated the corrosion process, the chloride-based salts being the most aggressive ones, followed by the carbonate-based and the nitrate/nitrite-based salts, respectively. The L-PBF 316L did not react strongly with the nitrate/nitrite-based salts, but some corrosion products not found in the samples tested in the absence of salts, such as NaFeO2, were formed. LiFeO2 and LiCrO2 were identified as the main corrosion products in the samples exposed to the carbonate-based molten salts, due to the high activity of Li ions. Their growth produced the depletion of Fe and Cr elements and the formation of vacancies that acted as diffusion paths on the surface of the steel. In the samples exposed to chloride-based molten salts, the attacked area was much deeper, and the corrosion process followed an active oxidation mechanism in which a chlorine cycle is assumed to have been involved.

“…Viscosity increase is not an issue in this work as the PCM is stacked in the heat exchanger and does not circulate. The corrosion issue has been studied over a wide range of temperatures, from cold applications [13][14][15] to high temperatures [16], especially for concentrated solar power applications and thus with molten salts used as PCMs [17][18][19], passing the building temperature level [20][21][22]. Fewer studies have focused on the medium temperature range that concerns us (120-150 • C) [23]: a recent paper investigated the compatibility between a commercial PCM named PlusIce S83 (mainly composed of magnesium nitrate) with aluminum, copper, and carbon steel [24].…”

Thermal energy represents more than half of the energy needs of European industry, but is still misspent in processes as waste heat, mostly between 100 and 200 °C. Waste heat recovery and reuse provide carbon-free heat and reduce production costs. The industrial sector is seeking affordable and rugged solutions that should adapt the heat recovery to heat demand. This study aims to identify suitable latent heat materials to reach that objective: the selected candidates should show good thermal performance that remains stable after aging and, in addition, be at a reasonable price. This paper details the selection process and aging results for two promising phase change materials (PCMs): adipic and sebacic acid. They showed, respectively, melting temperatures around 150 °C and 130 °C, degradation temperatures (mass lost higher than 1%) above 180 °C, and volumetric enthalpy of 95 and 75 kWh·m−3. They are both compatible with the stainless steel 316L while their operating temperature does not exceed 15 °C above the melting temperature, but they do not comply with the industrial recommendation for long-term use in contact with the steel P265GH (corrosion speed > 0.2 mm·year−1).
