In this research, the focus was corrosion behavior of two stainless steels (UNS S30400 and UNS S31600) and a carbon steel (UNS G10180). These were tested at 700°C in a molten NaCl-KCl-MgCl₂ eutectic salt in static air and flowing argon. Electrochemical techniques were used to characterize the corrosion behavior.m
This technical report applies to water-using cooling and heating systems in buildings. It provides information for minimizing system damage and operational interference because of corrosion, scale, fouling, and microbiological growth in building heating, ventilation, and air conditioning (HVAC) systems. This includes open and closed circulating water systems, low-pressure steam boilers and hot water “boilers.” The document also addresses thermal energy storage systems, but does not address potable water or fire protection systems. It is intended for use by building owners and engineering, maintenance, and operations management personnel. It is also intended for use by those involved in the design and construction of building HVAC systems so that corrosion, scale, fouling, and microbiological growth problems described above can be understood, anticipated, and minimized through appropriate design decisions.
