Dear experts,
3" size SS piping (sa 312 tp 304) is found as leaking in few places (near to weld joint, base pipe area etc..).the service is potable water.sub- contractor saying it might be due to high chloride content (830ppm) or  defective material (leaks mostly found in 1 heat no.).which could be more relevant? If for material, what are the tests for confirmations?  Kindly share your views.
Thanks in advance,
Kumar.

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...
