![]() ![]() Uncovered shipment over roads where road salt was applied.Storage in improper conditions (for example, in coastal areas impacted by sea breeze).Exposure pathways are numerous, but some examples include: The greater challenge is avoiding inadvertent exposure prior to end use. Mitigating chloride exposure risk during normal use is relatively straightforward - just make sure you’re using the ideal stainless steel variant, or apply special coatings to boost resistance. If that’s not caught and addressed right away, this can evolve quickly into pitting corrosion. Strong chlorides can disrupt chromium oxide to form surface corrosion. ![]() But this barrier can be overcome in a few different ways. ![]() Unlike flaky iron oxide, chromium oxide clings quite tightly to the surface, forming the protective barrier that makes stainless steel so resistant to corrosion. Stainless steel owes its reputation (and its name) to chromium oxide, which forms naturally on its surface in ambient conditions. The whole supply chain must understand how it can happen, know what to do to prevent it and verify that others are being just as careful. That means that everyone who handles it -mills, distributors, fabricators, job site crews and all the shippers in between - is responsible for preventing contamination. That’s why they call it “stainless.”įact: It can corrode if it’s not handled properly.Įngineers in aerospace, semiconductor, biopharmaceutical and sanitary applications know the importance of preventing stainless steel contamination during regular use of a piping system.Įven so, stainless steel must be protected at every step in the long journey from origin to end use. ![]()
