RE: [MW:14280] RE: 14217] Flux-Electrode Combination required.

By Materials & Welding
Hi Ansari,
 
Please see the earlier discussion on the similar topic posted in ther forum.
 
Note other than "Mn" SA 516/70 steel does not have any alloying element, which can improve the mechanical properties after normalizing.Hence welding consumable with alloying elements are always advisable
 
Thanks

Generly Normalizing + SR of 7018 catagory weld will not give required UTS of SA516 Gr70  as it deteorates the value
Therefore It is recomeded E9018 with higher Mn for welding Gr70 CS which undegoes NR but However more than 50 thk weld  with more than 2hrs Soaking time of NR even E9018 is not suitable.In such case The D/E of Crown and petal construction is recomended (With B2 having Cr is not suitable for such NR condition)
Incase of SAW process there is no suitble wire and flux combination (Even EH14 is not good) some time you can try EA3 or EF3 (SAF 5.23) but not for higher thk 
To get good results you may high to make trials with NR time and temp

If weld is subjected to Normalizing and then Stress releiving, 7
serious electrode will not work out, after heat treatment strenght
will come below minimum requirements,
Pl go for 8serious loke 8018-G ( tenaloy 60/65) for SMAW and for SAW
go for alloy steel wire -B2

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...
