GT has extended experience of applications and corrosion of our grades with most chemical media.
Examples of corrosion charts comparison with metallic solutions ;
Corrosion charts are useful tools for engineer to decide material of construction of equipment. Unfortunately, most corrosion chart are given with fixed composition of media without pollutions of certain type of ions.
Metallic materials are sensitive to such pollution and would lead to dramatic consequence if corrosion tests are not conducted prior to investment decision.
This is especially true when the feedstock have variations of compositions (for example phosphate rocks for phosphoric acid process, biofuel produces from biomass using sulfuric acid)
As a matter of fact, graphite is not senstive to such ionic pollutions and you can rely on corrosion chart with more reliability.
