FATT test - X20CrMoV11-1
FATT test - X20CrMoV11-1
(OP)
Hello.
I need to define a procedure to perform the FATT test for the material X20CrMoV11-1.
In theory this procedure will be based in the standards A370 and ASME Section III NC2300.
I know that we need to perform some tests up to different temperatures to define a curve. What I don't know is which range of temperatures should we test for this material.
Do you know any paper or brochure or whatever talking about this?
Thanks in advance for help!

Is for that reason I am asking if anybody has experience with that.
Thanks.

Note that X20CrMoV11-1 is actualy a material for high temperature , so why would you be interested in its low temperature behavior. Secondly this material is not accepted for ASME Codes.
RE: FATT test - X20CrMoV11-1
The problem is that I don't have any experience with FATT.
FATT is only used in low temperatures? Can we perform it at 100°C for example or more?
And then, which procedure/standard should I use instead the ASME code? Which EN talks about the procedure?
Sorry for these questions if they sound stupid, but I am a bit lost.
Thanks!

Fracture appearance transition temperature (FATT) is a reference temperature obtained from either Charpy or other impact test to describe the ductile to brittle fracture behavior of a material.
There is plently of reference material on the internet describing what is FATT.
