Old ASTM A-265

Old ASTM A-265

Old ASTM A-265

(OP)
I have a very old column ( from the sixties) in which some shells and one head are in A-265.


The remaining is in A-285 Gr. C

Cladis S.S. over the whole colomn (inside)
design code is ASME VIII div.1.
Column is at 3.5 bag and 375 Celsius

I have to re-assess this column (chapter 4 and 5 of API 597)

My question is what is this A-265 ??
It looks like an obsolete ASTM material !!

How does it compares with A 285 Gr. C ??
What is its allowable stress say at 200, 300 , 370 degree Celsius.

Any idea, tips...Thanks

RE: Old ASTM A-265

ASTM A 265 is the Standard Specification for Nickel and Nickel-Base Alloy-Clad Steel Plate. It is not obsolete.

RE: Old ASTM A-265

carthago,

Your data seems to be inconsistent. You mentioned that the whole column is SS clad, and yet you mentioned that some portion is A265 and some are A 285 Gr. C

And why are you reassessing the column to API 597? API 597 is a withdrawn spec. for Steel Venturi Gate Valves

RE: Old ASTM A-265

My guess is the poster meant using API 579 fitness for service.

RE: Old ASTM A-265

I suspect that the SA285 Grade C was the base metal for the clad componenets.  Also reference to API-597 may be a typo for API-579.

I see you are awake..thanks

Sorry guys, I mean API-579 ( FFS for checking metal loss..since we have also corrosion under insulation).

You are right I Believe this A-265 is for the clad..
