[MW:24704] Re: Impact Testing

By Materials & Welding
Pl. elaborate @ - 48 Deg C

Why you want to use GR 11 for this temperature . ?
What are  impact energy values required ?
What is the thickness of pipie ?
PL note it is very difficult to get the energy values especially HAZ and WELD

Dear All
Need your expert opinion on below query.
 
We are working on new project with Pressure Parts proposed to customer in ASME A335 P11 materials.
 
Since the ambient temperature is -48C, we need to perform the Impact Test for the same.
 
We think that the pipe material can be impact tested. Since this test is not a standard requirement for SA335 P11 pipes no guarantee is provided on the resulting minimum impact energy.
 
Any suggestions ????
 

Warm Regards
Praphulla

Re: [MW:34105] SA266 GR4N 4 Cycle SPWHT

By Materials & Welding
Hi,  You are correct, Minimum refers to the one cycle for which this part will expose until final work shop PWHT. hence mill test certificate shall include this.  Max. SPWHT, refers to additional cycles of heat treatment that are reserved for future repairs during equipment lifetime.  Again, these simulated no. Of cycles shall be specified in MTC.  The idea is we need to make sure that steel mechanical properties are not compromised upon exposure to multiple repairs (i e 4 cycles in your case).  One could say, if steel is subjected to 4 cycles and is ok, then it should by defacto be good for one cycle, yet, this is wrong assumption cause mechanical problems and microstructure of materials varies accordingly based on no. Of cycles for which material will expose. This is apparent in alloy steel and especially for impact test values as an example.  In your case, this forged CS with properties before PWHT can be understood to be " as forged" condition (i.e. Wit...

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...
