Degradation of steel in gaseous hydrogen with inhibiting admixtures

We have investigated the possibility to protect metal constructional elements of power-generating equipment against hydrogen embrittlement by introducing O2 and CO + H2 O admixtures into the working volume. We have shown their positive influence on the mechanical properties of 03Kh12N10MT steel and...

Zusammenfassung:We have investigated the possibility to protect metal constructional elements of power-generating equipment against hydrogen embrittlement by introducing O2 and CO + H2 O admixtures into the working volume. We have shown their positive influence on the mechanical properties of 03Kh12N10MT steel and KhN60K16MBYu alloy under short-term and long-term static tension within the temperature range 293-1073 K in gaseous hydrogen with a pressure of 35 MPa. However, we have not detected an inhibiting effect of the admixtures mentioned above in the case of preliminary high-temperature hydrogenation of unloaded smooth and notched specimens made of 05KhN23MTR steel and KhN60K16MBYu alloy.
