Building hydrogen handling systems which can last and withstand embrittlement are vital for operational success and ensuring industry safety, an H2 View Showcase Webinar explained today.
Chuck Hayes, Global Technical Lead for Clean Energy at Swagelok, took attendees on a comprehensive materials science journey during the 45-minute online session, highlighting the materials needed to overcome hydrogen handling challenges.
Embrittlement is a key issue, on two fronts. As temperature decreases, metals lose some ductility, and atomic hydrogen can diffuse into the metal and cause embrittlement; -70°C is the point where embrittlement in austenitic stainless steel is the strongest.
