Plz help me regarding such full-form:

1. ASME full form of SA - A 387/A 387M – 06a ............. what does means of "SA" - "A" 387 ................. "A387M" - "06a"..........................???

                          or

             A 387/A 387M – 06a

2. Grade P91 steel (A 387/A 387M – 06a)
    what does me "P"  & "91"

American Society of Mechanical Engineers Section A, Developed by ASTM Commitee A01.11 A387/A387M is adopted from ASTM A387/387M where M stands for Metric; as Americans follow inch-pound system; 06 is year of publication, a-is first revision in that year

P91-P is desgination; 9%-Chromium, 1%Molybdenum

P91 stands for grade of the material , where P stands for pipe, 91 stands for 9% Cr, 1% Mo and Vanadium . P  no. Of grade P91 material is 15E.

Grade P9 has composition 9% Cr - 1% Mo whose P no. Is 5B.

“SA” is not an acronym.  It is just a designation given to the ferrous material specifications adopted by ASME to distinguish it from material specifications from other organizations.  There are also ASME “SB” specifications and they are for the nonferrous material specifications.  

 

The ASME SA- specifications are in ASME Section II, Part A and the ASME SB- specifications are in ASME Section II, Part B.  The latest edition is the 2013 edition.

SA is an ASME specification for the analysis of ferrous materials. A387 / A387M are the specification number for that particular material. 06a is the year when it was approved by ASME. While 'P" is the number assigned to that material because of its properties. the numerical figure 91 attributes the composition of elements it contains. I found the regarding info in www.weldpedia.com

SA: "S" stands for ASME material specification, adopted from ASTM. 

"A" stands for Ferrous material SA 387/M387M, is Pressure Vessel Plates, Cr-Mo Alloy Steel, SA 387 is in US conventional units(FPS), "SA 387M" is metric version, 06a is 2006 edition addanda.
