[MW:15710] interpretation of the sub size,impact value and the temprature reduction as per asme 31.3 (table 323.3.4)

By Materials & Welding
Dear experts
I have a dout in the interpretation of the sub
size,impact value and the temprature reduction as per asme 31.3 table
323.3.4) and the material code (asme sec 12A for sa350 LF2,333GR6
table 5 and table 6 )
question is :- If the test piece is 3 inch sch 40 (thicknes 5.49)
and the thickness of the machined specimen for the impact is 5 mm
(more than the 80% thickness of the test specimen).do we have to
perform the impact test on the specimen what will be the test
temprature -46 deg centigrade or -57 deg centigrade.
and what will be the impact value required for single and average.

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...
