Relationship between HCL corrosion and temperature
Thread Content
I’m very curious to know what the relationship is between HCL corrosion of metals and temperature ? ?
The higher the temperature, the more severe the corrosion!
It is related to concentration; at a certain concentration, there is a temperature range in which corrosion occurs most rapidly
Is it pure HCl gas or hydrochloric acid?

What is the corrosion situation with pure hydrogen chloride?
The critical temperature at which high-temperature hydrogen chloride media cause severe corrosion of steel is 300°C; when the temperature of the medium is below 300°C, the corrosion is relatively mild. Therefore, the furnace wall temperature should be maintained above the dew point and below the critical corrosion temperature at high temperatures; thus, a range of 100°C to 300°C is optimal.
