A new class of carbon stabilized austenitic steels resistant to hydrogen embrittlement

Heena Khanchandani, Stefan Zeiler, Lucas Strobel +2

High strength steels are susceptible to H-induced failure, which is typically caused by the presence of diffusible H in the microstructure. The diffusivity of H in austenitic steel…
