CORROSION HANDBOOK06/2021206/21FOREWORDCorrosion is a ubiquitous natural process. Most of us, at some point in our everyday lives, become familiar with the effect that CORROSION has on rusted steel parts. CORROSION has a huge economic impact. About a fifth of the world s annual steel production simply goes towards replacing parts damaged by CORROSION . Even though it may involve higher up-front cost, correct and efficient CORROSION protection at source helps save money and resources in the long run. For fastening systems, it s even more critical because safety is key. Failure due to CORROSION may have dramatic goal of this HANDBOOK is to raise your general awareness of what CORROSION is all about. It provides you with essential information on CORROSION and the behavior of the materials used to protect our products from conducts comprehensive laboratory and field-based tests to assess the CORROSION resistance of its products.

hindered, whereby the cathodic partial reaction (see 1.1) preferably takes place only outside the crevice. The crevice area itself becomes the anode, and thus the preferred region for metal dissolution. (see Fig. 7). It may also occur under washers or gaskets, when the entry of water underneath is not prevented (see Fig. 7).
