Re: [MW:27695] Re: WPS base metal qualification range

Two materials are mentioned in the original mail P5A and below in that mail mention P15E, I guess there is a confusion here, specifically I refer to the material P5A, THAT WAS THE POINT THAT I EXPOSE.
Please see attached image.



Hi 

This is Srinivas, 

I got a PQR P5A to P5A , So i can write WPS P5A to P4 from that P5A to P5A PQR ? 

Based on QW 424.1 ?

But P number is an essential variable so what is the actual 
interpretation of the above clause 

Or does it means if we qualify procedure for P15E +P4 then it is 
qualified for the P15E any metal from this group to any metal from 
P4,P3 P1 groups

You have to read QW 403.1 and then QW 424 carefully. Your interpretation is wrong . If your PQR was done using a P15E and a P4, then you can support WPS which are for any P15E to any P4 ONLY

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

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

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...
