Hydrogen that that impacts carbon steels, once impacted it makes the spring material brittle and susceptible to cracking and failure, particularly under sustained loads.
Hydrogen has the ability to damage very powerful steel. The High strength steel. Once the hydrogen makes contact with the steel it becomes brittle. This actually shows that there’s a way to make steel breakable. If you have a stainless steel compression spring that will be exposed to Hydrogen you might want to take this into consideration. It was in 1875 when this first was recognized publicly. This will tell you a lot about the power of hydrogen and steel.
This process of hydrogen embrittlement can occur during manufacturing processes. Or at any moment where there’s contact made between the hydrogen and the metals.
