In this case, the surface area of the aluminum is so large relative to the surface area of the stainless steel bolts that, there is a very low risk of major corrosion.Chloride/Chlorine Levels and Stainless Steel Alloy stainless steel pipe for acidic environment useThe 304 and 304L (18-8 stainless steel alloys) have been utilized very successfully in fresh waters containing low levels of chloride ion of up to 100 ppm. This level of chloride is considered to be the limit for the 18-8 alloys, particularly if crevices are present. Higher levels of chloride might cause crevice corrosion and pitting.

Keeping stainless steels stainless - The FABRICATOR

Causes of Corrosion. Stainless steel's corrosion resistance is due to a thin, chromium-rich, transparent oxide film on the surface 1.This protective film develops when more than 10.5 percent of chromium is present in the alloy and when the gas or liquid environment the stainless steel is exposed to provides oxygen to its surface.Life Cycle Costing and Stainless SteelThe environment and scope of usage are therefore crucial in determining the LCC benefits when choosing stainless steel. An example of a bus frame is shown in Figure 2. This shows that, when considering the total life of the bus, stainless steel is clearly the cheaper option.Life Cycle Costing and Stainless SteelThe environment and scope of usage are therefore crucial in determining the LCC benefits when choosing stainless steel.
