zulsaid,
350-LF2 has two different grades, be sure to specify Class 1 for that 'low' temperature range as it is suitable to -50F; Class 2 is only rated as low as 0 degrees.
Sorry to anyone who read this already, I also posted in the Vessel forum.
Is there any merit in normalizing SA-106-B?
I'm on a job now where the request is as per above for use on vessels subject to sulfide stress cracking. I've heard people say that SA-106-B has no merit to normalizing as it...
The below link will help convert between HRB and HRC. The way I see it, ASME has a maximum hardness of 17 HRC, NACE has a maximum hardness of 22 HRC. It seems like a no-brainer, but don't lose sight of the other requirements regarding annealing and cold work. Although it may appear as a...
Frank,
I think it comes down to hardness values. NACE MR-0175, paragraph 3.5, accepts 316L provided the hardness value is 22 HRC max in the annealed condition. As per Section II Part A, 316L has a maximum hardness value of 217 Brinell or 95 Rockwell B.
The problem here is these are different...
300W has a higher yield (44 ksi) than SA-36 (36 ksi). In my opinion, 300W is an overall stronger material. Anywhere SA-36 material is specified, 300W is generally an acceptable substitute (not necessarily every application). However, I would not automatically accept SA-36 in lieu of 300W due...
The material spec in question is already ASME certified. Refer to ASME Section II Part A (page 1637 of my edition)and you will find the spec you are looking for titled SA/CSA-G40.21. If you call off the material accordinlgy, you should have no more problems.
