[Analysis Case] Analysis of Hydrogen Desorption from Stainless Steel by TDS
It is possible to evaluate the amount of hydrogen released from metals using TDS (Thermogravimetric Desorption Gas Analysis).
Many metallic materials, such as steel, are known to deteriorate (hydrogen embrittlement) due to diffusible hydrogen that diffuses within the crystal lattice at room temperature. This time, we present an example of evaluating the amount of hydrogen desorption from stainless steel plates (SUS316L) with added hydrogen using TDS. A desorption peak, thought to be diffusible hydrogen, was observed in the low-temperature range around 150°C.
