Hydrochloric acid is a most common acid using graphite material.
Graphite is fully corrosion resistant over the whole range of temperatures and concentration.
Our grade GT KELITE+ with phenolic resin bring reliability for processes using hydrochloric acid.
Unlike most metallic grades, graphite is not sensitive to pollution of media with fluorides or other compounds. Most corrosion chart consider “Clean” media. Only 50ppm in fluorides in hydrochloric acid will corrode tantalum and other alloys.
Graphite is the best choices for composition with variable concentration and unwanted pollutions.
We can proceed to corrosion test or provide coupon for test on request here.
Synthesis units with hot hydrochloric (1500degC), can be cooled and absorbed into GT TOWER, GT TUBE or GT BLOC using our GT CARB+ material which can handle up to 500degC with air (up to 1500degC in reducing atmosphere).
