[MW:28902] RE: PQR Query

By Materials & Welding

Darshan,

 

Both grades are P No 1, Gr 2, according to ASME Sec-IX. However SAES-W-012 imposes the following restriction, which is more binding. In that case PQR needs to be qualified/requalified on API 5L X60 . Hope this answer would clarify your doubt.

 

Thanks.

Dear Sir,

Can you  suggest on PQR qualification.

 

I am having Forging of SA 350 LF 2 grade in pipe shape and my production joint material is API 5L X60.

 

Now can i qualify PQR with avilable material for production joint. Is there any restrictions as per SAES-W-012 like qualification material shold be from API grade only.

 

Regards,

Darshan

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...
