Re: [MW:32256] welding api 5l x52 with x60

By Materials & Welding

As per API 1104 , 2013 edn, Clause 5.4.2.2 , you can use the same WPS without requalification. I presume your flange and fittings are having same SMYS ( Specified Minimum Yield Strength)  and similar CEq

 

Requalification is required only when the base metal welding involves less than X42 or greater than X65. In your case this is not applicable.

 

Make sure, Your WPS have mentioned : Qualified Base material X42 Through  X60.

 

            Keeping future qualification purpose, it's better to qualify PQR with X65 material which many customers accept for all lower grades' base metal qualification.

Thanks and Regards

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...
