ASME SA 240 Mat'l Identification

ASME SA 240 Mat'l Identification

ASME SA 240 Mat'l Identification

(OP)
I have been trying to identify the material used on one of our applications.  I have found the material stamp and its manufacturer.  The material does not have an AISI number that I have found though ASME, but I did find a material in SA-240 of Section II that has the exact composition.  The AISI UNS# is S43940 and it has an EN#1.4509.  Another European company, is saying that there is an AISI # 441 for this same material, but this is the only reference to this AISI#441 that I have found.  Can I determine from the SA-240 chemical composition match that it is an acceptable material?  I believe that is the case, but please give me your input.  Please advise.

If you have the material stamped with an SA 240 UNS number this is sufficient for identification purposes.

Basically, I have a metal part that was made in Europe.  The only part of the metal ID stamping I can make out is "1.4509", which is an EN identification.  I am trying to decide if this material complies with ASME Section II, SA-240 for sheet.  The "1.4509" chemical composition matches the S43940 composition in SA 240.  Is this enough to say the material complies?  This is first time I have dealt with the ASME code, and I guess the interpretation is not so clear.   

RE: ASME SA 240 Mat'l Identification

eeme;
I now understand your OP. You would need to have this material certified for use under ASME B&PV Code. There are provisions for doing this, it depends on which part of the B&PV Code of construction you are following. If it is Section VIII, Div 1, there are rules for certification of material that is supplied under a UNS designation, but not an SA specification.

Metengr,
Thanks for the valuable information.  I will take it from here, and this gives me a good start.

The chemistry may match, but does it have the correct thermo-mechanical history?
At least you have a place to start now.
