Material selection for lead-bismuth alloy pipes
Thread Content
The company currently has a project involving lead-bismuth alloys. The operating temperature for these alloys is around 500°, with an operating pressure of approximately 3 MPa. Regarding material selection, reference should be made to 20801.2; it seems that austenitic, ferritic, martensitic, and duplex stainless steels cannot be used. There will be hydrogen in the pipeline as well; experts, please help analyze what kind of material should be used for such a pipeline!

The papers related to your medium seem to all be in the field of fourth-generation nuclear reactors, with the lowest level being master’s theses
I’ve never heard of this material. Sorry!
316L still belongs to the austenitic stainless steels; it cannot be used according to standard 20801.2. What material is P91?
