Re: [MW:26945] Alloy PMI after PWHT(piping)

Dear Friend,

It is hardly a matter of concern if PMI is being carried out before or after PWHT.
The ultimate purpose of PMI is to ensure that the material contains required chemistry or not.
There is no harm also if the same is carried out before PWHT.
It is not like RT when it is preferred after PWHT to know if there is any repair specially crack has been developed after PWHT.

Hope I answered your query.

Regards,
Rajnish

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...
