Non ferrous material-ASME GRADE

If we do all the work for you, what will you do?

This question is much more difficult than my question. GURU is supposed to and must guide the followers like us!

The fact is that these data are all available by putting the material description into an internet search engine. So, who is going to do it?

"GURU is supposed to and must guide the followers like us!" That's a crock!

You're wanting someone to do the work for you. It won't be me.

Ask your material supplier! They are the ones who will make money on this. Let them do your job for you.

Have you ever used any of the materials web sites availaable to EVERYONE on the web?

Old saying:

"Give a man a fish, he feeds for the day.

Teach a man to fish, he feeds for life."

Incoloy 825 is not non-ferrous, it has substantial iron in it.

After a brief search on google:

Incoloy 825 equivalent ASME grade is SB424(for pipe)...Now pls refer ASME SEC II-B , which is the applicable code for Non ferrous materials.(ASME SEC II-A is for ferrous materials)

Kindly clarify why this material is included in non ferrous materials code even though it has subtantial iron in it?

(Reference: ASME SEC II, part-B, 2007 edition, page-567)

A man in EIL or Technip asking this type of detail from out side is surprising, and the reply by a GURU is appropriate, if we work for you to arrange details, what you will do?

If you would have posed some technical difficulty then the forum would have worked out the solution with healthy discussion but just collecting data from this type of forum is dificult man !!!!!!!!!!!!!!!!!

I was incorrect, it has about 22% iron, it has 38-46% nickel, so it is primarily a nickel alloy. inconels have no iron to speak of, incoloys do.

625 is not an incoloy, it is an inconel. what determines is which element has the largest percentage. I had in the back of my mind that 825 had primarily iron as it's major ingredient, but I was incorrect, it has more nickel and chromium than iron. incoloys have large percentages of all three, inconels generally have very little iron.

Not to mention that both Inconel and Incoloy are trade mark names owned by Special Metals- other companies make the same metal with different names.

EIL is already supposed to know ALL of PetroChem in India

Now a lot of technical info is available, but the basic question which remains is that why they are called as non ferrous materials even though incoloy 825 has 22% iron and inconel has around 5%.

Is there any iron/chemical restriction to classify an alloy as non ferrous?

I think Rorsarch in answer #11 has what you ask for.

It do not have any reference but I think alloys which contains less then 50% iron as one of the constituents, falls under categary of non ferrous alloys.
