X63 material

X63 material

(OP)
Hello everybody,

somebody knows the material X-63?
I suppose it is an very old API designation (API 5L X-63 Gr.B)
Am I right? In which standard version can I find it?

Best regards
juan

seams to be an NF material...

RE: X63 material

X63 can be a designation of the actual API-5L:2007 resp. ISO 3183:2007.  It is possible to use intermediate grades (intermediate to two sequential standard grades).  This possibility already existed in the previous editions 2004 and 2000.  Grade B is also a grade designation of API 5L, but is not the same than X63.
