Re: [MW:13063] Welding of AISI 316L to A516 Gr B regarding

By Materials & Welding

Just 309 is ok. 316 with carbon steel will give hot cracks because of low FN. You need a filler metal with much higher Cr and Ni content to avoid low FN

  Subject: [MW:13062] Welding of AISI 316L to A516 Gr B regarding



Good day to all,
Please refer the attachment  for joint configuration, I have to qualify the procedure for AISI 316L to A516 Gr B steel
Thickness of the job maximum 64 mm. I proposed to use 35 mm thickness plate for qualification.Code requirement ASME Sec IX
My plan as follows
1) Buttering the Bevel area of A516 Gr B material using E 309 consumables up to 3 to 5 mm
2) Machining of Bevel & PT (NDT) & Fit up
3) Welding of A516 Gr B to to AISI 316L using E316 consumables 

Kindly  advice me what preheat temperature  & Interpass temperature can maintained during welding, Any PWHT required or not,any other precautionary measures during welding & mechanical testing.
My client not specified anything. Please someone advice to me.
Thanks
Regards
E.Jegan

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...
