Re: [MW:12921] Welding of SS 316 to A 36 Steel reg

By Materials & Welding
Hi,

Due to heavy thickness PWHT is mandatory, 1st butter CS flange with 1 or 2 layers of ER309 and do PWHT, this avoids PWHT that might sensitize Austenitic SS to intergranular corrosion.

After machining and inspecting the buttered layer, you can use conventional SS welding mthod.

In case of elevated temp.Inconel is used.

Subject: [MW:12893] Welding of SS 316 to A 36 Steel reg
Good Day to Group members,
 
I have to weld SS316 64 mm thickness pipe to Flange A105 64 mm thick by Double bevel weld, Code requirement API 1104 latest edition / ASME Sec IX requirement, Can you tell me SMAW & SAW process which cl-assification electrode can use for this joint, Any Buttering requirement using E309 Electrode on carbon steel side before welding with E 316 electrode, What preheat temperature & interpass temperature maintain during welding. Please share your experience & Give suggestions to get good quality weld.
 
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...
