Industries namely, the ones involved in processing tend to have up-set conditions. This means the process alternates from a reductive to an oxidative one in a fraction of a minute or an hour. Hence, the processing industry rightly labels them as upset conditions. Since the components involved in these industries need to be resistant to corrosion, especially against pitting and crevice corrosion. The best components for the above issues are the Stainless Steel 904L Flanges because their corrosion resistance properties range from moderate to high in upset conditions.
The high content of both chromium and nickel makes it a super austenitic stainless steel alloy. This term is given to those alloys whose PREN value is higher than 40. The PREN or pitting resistance equivalent number of the En-1092 Ss 904l Forged Flanges is a value that indicates how good is its resistance to pitting. Typically alloys whose PREN value is around 38, are regarded as being highly resistant to pitting. The PREN value of materials is higher if the content of molybdenum is greater or equal to 6%. The high resistance of the Din 1.4539 Ss Socket Weld Flanges against pitting is attributed to the inclusion of maximum content of 5% molybdenum in its chemical composition. Pitting is reduced because molybdenum increases the efficiency of the passivating oxide layer formed on the alloy. Therefore, the upper layer of the Stainless Steel 904l Slip On Flanges remains protected, and the rate of pitting is drastically reduced. Moreover, the high temperature strength of this alloy remains good because of the inclusion of a maximum of 28% nickel in its chemistry. Although the alloy has a high pitting value, one of the main reasons for developing it was for industries that involve sulfuric acid, which is highly corrosive. Processing industries that use this acid, may require Uns N08904 Pipe Flanges because they can withstand sulfuric acid at varying concentrations, up to a temperature of 95°F.
