[MW:34469] Re: ASME full form of SA - A 387/A 387M – 06a

By Materials & Welding
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.

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

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"

Heat tint (temper) colours on stainless steel surfaces heated in air // Heat tint

By Materials & Welding
Introduction The colour formed when stainless steel is heated, either in a furnace application or in the heat affected zone of welds, is dependent on several factors that are related to the oxidation resistance of the steel. The heat tint or temper colour formed is caused by the progressive thickening of the surface oxide layer and so, as temperature is increased, the colours change.   Oxidation resistance of stainless steels However, there are several factors that affect the degree of colour change and so there is no a single table of colour and temperature that represents all cases. The colours formed can only be used as an indication of the temperature to which the steel has been heated. Factors affecting the heat tint colours formed Steel composition The chromium content is the most important single factor affecting oxidation resistance. The higher the chromium, the more heat resistant the steel and so the development of the heat tint colou...

The Schaeffler and Delong diagrams for predicting ferrite levels in austenitic stainless steel welds

By Materials & Welding
Introduction Ferrite is important in avoiding hot cracking in during cooling from welding of austenitic stainless steels. 'Constitution diagrams' are used to predict ferrite levels from the composition by comparing the effects of austenite and ferrite stabilising elements. The Schaeffler and Delong diagrams are the original methods of predicting the phase balances in austenitic stainless steel welds. Nickel and chromium equivalents A 'nickel equivalent' is calculated for the austenite stabilising elements and a 'chromium equivalent' ferrite stabilising elements. These are used as the axes for the diagrams, which show the compositional equivalent areas where the phases austenite, ferrite, martensite (and mixtures of these) should be present. Although intended to show the phase balance of weld fillers, these diagrams can also be used to illustrate the phase balance of the 'parent' material. There are different diagrams for dif...
