As discussed earlier, the thin layer of chromium oxide on the outer layer helps stainless steel fasteners to self-repair, which is remarkable. This is done as chromium produces oxidation to fight oxidation. This method is very innovative, making stainless steel is a top choice for all types of fasteners. If any dent or damage is made to the fastener, it exposes the bare alloy on the fastener’s damaged part to oxygen. This causes oxidation, and another layer of chromium oxide is formed, protecting the fastener from further corrosion.
