Yes, these alloys are strong enough to perform reliably in hydrogen fuel vehicles. When looking at the strength of an alloy, we look at two parameters: Tensile strength and Yield strength. The yield strength is the value beyond which the alloy will deform permanently. On the other hand, an alloy will break if its tensile strength is exceeded. That said, our tubes manufactured from these alloys are reliably strong for their specific applications in hydrogen fuel vehicles.
