Are there any data available for Q345R material in a hydrogen corrosion environment? By looking at the Nelson curve, there’s no need to worry about Q345R. Beyond carbon steel, it’s 15CrMo. Does anyone have data on Q345R material in a hydrogen corrosion environment? It should be better than carbon steel, right?
Nelson addresses hydrogen corrosion under high temperatures and high hydrogen partial pressures; chromium-molybdenum steel is considered only at temperatures above 200 degrees, while Q345R(HIC) material can be used in low-temperature hydrogen environments
The unit is already in a hydrogen-corrosion environment; the operating temperature in the heat exchanger’s tube side is 310 at the inlet and 150 at the outlet, with an operating pressure of 4.2 MPa, and the hydrogen concentration is 99%. I just want to know about the materials that Nelson didn’t mention, after all, Q345R is quite commonly used
When the temperature reaches 300°C, chromium-molybdenum steel is required in such conditions. Although Q345R is a low-alloy steel, it should fall under the category of carbon steel, right?
