.... Specifications Type 309 stainless steel was originally chosen after consideration of potential dew-point corrosion, thermal cycling, high-temperature chloride attack, and material cost. Because the operating temperature is significantly higher than the dew point and the system is operated for at least 30...

... and testing if atmospheric ammonia vapors condense on surfaces when the temperature of the circuit breaker components are below the dew point. Films can also form during service in humid atmosphere when trapped ammonia gases diffuse out of the phenolic case and cover and attack the contacts. The degree...

... of maraging steels should not exceed the maximum limit, because the notch tensile strength 1 as well as the toughness 2 have been shown to be detrimentally affected. Decarburization is a loss of carbon from the surface of a hardened steel part usually caused by an excessively high dew point or low carbon...

Otherwise, it can be the result of a mistaken choice of materials or of miscalculation of the corrosive effect of the medium circulating through the heat exchanger. For example, an acid-containing vapor stream may not be corrosive above its dew point...
