Grade 904L, unlike several austenitic stainless steel alloys, has a high degree of copper added to its chemical composition. The inclusion of copper in this low carbon containing grade is known to increase the corrosion resistance properties of the 904L stainless steel sheet. For example, this alloy can resist corrosion when subjected to sulphuric acid, which many of us know is a strong reducing acid. The resistance to sulphuric acid is very useful especially since the 904L SS Rings can withstand this acid at all concentrations. A non-stabilized alloy, the inclusion of molybdenum in its alloy gives 1.4539 Material an advantage over grade 316.
The metal can resist decay in the form of crevice corrosion and pitting when subjected to highly corrosive chlorine ions. Since the ASTM B625 Uns N08904 Circles includes various amounts of elements as alloyants the material has the ability to withstand chlorine induced stress related corrosion cracking. However, this chemical composition of the ASTM B625 Ss 904L Shims isn’t fully suited to combat the issue with SCC. One area where is alloy outperforms both grade 304 as well as 316 is with regards to intergranular corrosion. The low content of carbon included in the chemistry of the 904L Stainless Steel Plate leaves no free carbon atom for the precipitation to occur during welding. And since there are no precipitates on the HAZ or heat affected weld zone, the UNS N08904 Material will not be susceptible to intergranular corrosion.
