[MW:3082] Re: Regarding the NDT to be carried out for 60 mm thick austenitic stainless steel plates

High Curie or Low Curie only helps in time factor. But Ir 192 Penetration is same from Low and High. If am wrong correct me.

hi,
           you can go for high strength - 192, but dont go for cobalt 60 since we use for thickness ranging more than 100 to  & 150 mm above.

Hi,
If your specification permits for RT or UT you can carry out any of these test for 60 mm Thick S.S.
For RT you may need cobalt 60 or High strength iridium 192.
For Ultrasonic Testing you shall use the RTD Twin crystal longitudinal wave Angle probes.

Nilesh Pathare.

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...
