Re: [MW:4673] ER70S-3 for low temperature application

Then you will find your answer in USC-67.
If you do not have the code or you have interpretation problems let me know.

Hi members,

 

Please provide a suggestion for the following query.

 

I have qualified a PQR for GTAW+SMAW with ER70S-3 & E7018-1. The PQR is impact tested at - 46 deg C at root(GTAW) and filling (SMAW) and passed (Min. 50J energy obtained).

 

As per ASME Sec.II part C, E7018-1 will support up to - 46 Deg C, but ER70S-3 will support up to - 20 Deg.C only.

 

Since I have proven the toughness through PQR, can I use this PQR for job with impact test requirement of - 46 Deg C, even ER70S-3 does not support for this temperature as per Sec.IIC?.

 
Thanks & Regards
Muhammed Ibrahim PK
