It is not a Code requirement to PWHT the fillet weld between P91 pad and CS support since the pad is not a pressure part.
However I would suggest that you do a PWHT to this weld, especially if you have a corrosive environment.
You could propose a monitoring plan for those welds, but it will be difficult to implement it since I suppose that this line will be insulated.
You may save a lot of trouble in the future if you do a PWHT for this fillet weld.

Dear experts,
PWHT is done on pipe(P91) to pad (P91) weld. Is it required to do PWHT on pad (P91) to support shoe (CS) fillet weld. Please refer the attachment for details.

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...
