10CrMo9-10 P no:5A or Unasigned Material ?

10/20/2016 5:18 AM

Dear All

According to ASME Sec.IIA SA/EN 10216-2 is identical with EN 10216-2:2002 + A2:2007 with additional marking requirements.

Table QW-422 of Section IX lists the material as "SA/EN"10216-2 10CrMo9 , not

Is it possible to consider 10CrMo9-10 pipe as P number 5A acc. to Section IX Table QW-422 ? Or this material is unassigned as itself?

In case the answer is no; I recertify this material acc. to Section VIII Div1 or Div2. With this recertification, can we include it in P no 5A?

ps*: Material will be used in PQR test.

Thanks

That would all depend on the contractual requirements agreed to by your customer and your company.

Let me guess. The correct material is available, but more expensive, and you are trying to increase your profit margin by using an inferior material. Correct?

This question should be presented to the customer, with full disclosure of the reasons and your justifications.

Actually, my question is not based on a current situation, just for a knowledge, from your experience in general manner. The important is what Code says for me in this situation.

Thank you

You need to compare chemical composition and mechanical properties of both materials before conclusion.
