Re: [MW:22305] Welding of Inconel 625 & Incoloy 825

By Materials & Welding
Dear Sirs,

Noted your valuable suggestions. Hence we are using same filler material for these two materials, please advise whether we need seperate qualification is needed.

Thank you,
LALU

Hi!
Generally it is always preferred to weld Inconel 825 by NiCrMo3 rather than NiFe Cr1 (Equivalent of 825) due to avoid fissures like defect after PWHT

Hi Lalu,
 
Even though the chemical properties of ER NiCrMo3 not fully matching with BM chemistry of  Incoloy 825 , this filler alloy is widely used because of its availability.
 
Please look into the attached PDS of ERNiCrMo-14 (Thermanit 686) which is a matching filler alloy and suitable for higher temperature service conditions.
Hope this helps…

Dear Experts,
 
Can we weld Incoloy 825 with inconel 625 consumables ? Since both are under same P number but the chemical combination is different.
 
Looking forward your valuable response.
 
regards,
LALU

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...
