4 HOW TO ASSESS CORROSION IN
A SPECIFIC ENVIRONMENT AND
APPLICATION
The following section describes ways to help determine the corrosivity of certain
environments. The parameters influencing the corrosion can only be checked by
specialists working locally on a specific project. Accordingly, the final decision
regarding the chosen material and products is the responsibility of the user and/
or specifier. While Hilti personnel can provide you with the necessary basic
information about our products, it is not possible for them to carry out a fully
comprehensive check of the expected corrosivity of the intended application.
4.1 Factors influencing atmospheric corrosion
Under specific circumstances, the corrosivity and, respectively, the corrosion
rates of zinc and steel products can be estimated when typical atmospheric
parameters are known for a certain application (see Fig. 36).
