Carbon steel and low alloy steels are subject to excessive hydrochloric acid corrosion when exposed to any concentration of HCl acid that produces a pH below______.
Carbon steel and low alloy steels are subject to excessive hydrochloric acid corrosion when exposed to any concentration of HCl acid that produces a pH below______.
Carbon steel and low alloy steels are vulnerable to hydrochloric acid corrosion when the pH level falls below 4.5. At this point, the acidity is strong enough to cause significant degradation in these materials.
Carbon steel and low-alloy steels are subject to excessive corrosion when exposed to any concentration of HCl acid that produces a pH below about 4.5
