[MW:31133] Re: 31131] CS with Duplex SS (S31803) clad vessel PWHT?

By Materials & Welding
its in design stage,  process data  states as solid S31803 -42mm thick(with an option to use CS+clad), however use of clad plate might be difficult due to PWHT, as the thickness of backer plate will be >50mm.

Hi,

Discussions on the identical issues had taken place in this forum few years ago. I'm' reposting the discussion and the provided answers. It would be helpful to get the drawing or the tech specs so as to provide meaningful answers.

Thanks.

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...
