[MW:24479] 304L welded with filler 316L wire.

dear sir

 304L mat weld with ER316L filler wire. Process : TIG & THK: 5.49.

serivce : potable water.

i check Cr-Ni equivlent (https://www.ewm-group.com/en/practical-knowledge/welding-calculators/schaeffler-diagram.htm)

304L with ER316L has 23.23/15.77 and FN 10.38 and PREN is 29.90 

304L with ER 308L has23.06/13.68 and FN 15.20 and PREN is 24.48 

 means sir, 

 ER 316L is better choice for 304L is it true? why we used ER308L?

Heat tint (temper) colours on stainless steel surfaces heated in air // Heat tint

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...
