Re: [MW:29120] Re: Equivalent ASTM material for EN S275JR

These are structural steels but with impact test requirements. You probably know what J and K stand for or R etc. So You can consider them as P-No.1 materials but with higher grades like 335, you have CS in heat treated delivery conditions (N/Q/NT/QT etc) so they may have different group numbers.

Please note that you should not expect to find exact equivalent but there are grades which are practically the same. You may refer ASTM document DS67 for comparing different Steel standards. but again, you may not find the exact equivalent. 

European classification is more precise for structural steels. ASME is not "known" as detailed as Euro-norms when it comes to structural steels. Of course, P-No./Gr-No. classification in ASME is still reliable and useful but my recommendation is not insisting on finding an equivalent grade for your material further than P-No/Gr-No. You can see this with J or K grades which are not well-distinguished in ASME, not mentioning impact test temperature requirements or weather resistant grades.

As per AWS D1.1 unlisted material subjected to New WPS  i agree.

but if 275JR to 275JR wps can we  considered to other grades those material impact properties  are not effecting (temp  )

 Can we consider   these are  single Group (235JR,,275JR,355JR) and weld wrto 275JR approved WPS.

Dear,

you cannot get exact equivalent.

But nearby grade is ASTM A36
