[MW:4307] SSCC test for Welding in sour application.

By Materials & Welding
We have carried out a SSCC test on the welding of API 5l Gr 60 pipe as per NACE TM 177 and ASTM G 36.
As per the lab test report which I have not physically verified out of 12 specimens one has failed.
As per the client spec requirement there shall be no cracks after 720 hrs. What is the normal acceptance criteria for this test as per code.I dont hav access to both the mentioned codes.
And also if a retest is allowed.Our major problem is already we hav welded using this WPS.

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...
