Hi

We have to produce a material according ASME III Div 1 section NB.Material design temperature is 300°C.
There is no special requirements from our customer about material, just to be according to ASME Section II part A .
For our example , material shall be according to SA 182 Gr F304L.
Is there something about hot tensile test , and product analysis in the code?
Who is responsible to decide if these tests are required?
I have not found something about that in the sections of the ASME III Div 1.
Thank you for your help.

I am afraid you are confusing the Code. Maybe you mean Sect VIII Div.1 (Unfired Pressure vessels). In any case you don't need to make hot tensile testing but only to apply the "S" (maximum allowable stress) for the Code of construction and for the design temperature in Sect.II/D

chti,

For Section III material please consider NB-2000 and SA-182 in your case
Anyway, hot tensile testing is an option that is required only when so specified by the purchaser.

In order to supply such material, you need to have an ASME QSC Certificate, or be qualified by your customer. In either case, your Quality System Program should be helpful in supplying the material.

Hi,

I have made a mistake! I would say ASME III instead ASME VIII.
Thank you for your answers.
I note, that according ASME III and Subsection NB, it's not required, and only an option.
