ER 70 S2 and E 7018-1 do not give consistent impact at -46 Deg C . Many failures are reported.  For guaranteed impact at -46 deg C ER 80SNi 1 Can be used Sometimes there are restrictions in some services due to preferential weld corrosion problem.

Both materials are 70 KSI grades, hence matching filler wire is ER 70S types.

mr kiran all ready you got your answer why you are not trying to understand creating new misunderstanding again n again. see your requirment is not requirment of Asme its requirment of client on the basis of their experience client simply wants to know after doing heat treatment  3 times what property they are getting what is change in behaviour of material,weld  simply is there increase or decrease in prop he wants to know for that you also look at your tdc or mtc client asked for simulated plate also. now lets talk about welding- qw407.2 is only and only applies when your base metal / weld metal is not exempted from impact test.what code said in this clause  heating,colling rate, time, temp is should be same as of wps during soaking period. secondly if you have a any old wps which has same rate of heating,colling ,temp and wps time is 80% of time required in pwht for vessel. now simply calculate time for single pqr what ever time you will get multiply it by 3 you will get total time ...

If it is for the Plates during the procurement stage, then you need to follow the same Heat Treatment simulating the exact condition it undergoes. 1. Initial Heat Treatment for the Plates will be the first cycle. 2. PWHT after welding will be the second cycle 3. Taking into account the Repair after PWHT will be the 3rd cycle. You can simulate the same condition on one coupon and undergo the test as per Material standard. If it is for Welds, then you can apply PWHT in one cycle as the snap short  below. One Coupon and the testing requirements as per ASME Sec.IX and applicable specifications. Thanks & Regards J.Gerald Jayakumar ...

Hi, S31254 is under ASME P.No.8. SA516 Gr.70 is P.No.1.

Hi, Since this is P.No.1,Low temperature material, why do you go for ER80S-Ni1 ? Its used for weathering steel and corrosion resistant applications. It can be used to weld SA350, LF5 (P.No.9A) which is 1.5Ni steel SA350, LF2 and SA333 Gr.6 are C-Mn-Si steel (P.No.1), for this ER70S2 or ER70S-6 are fine.
