[MW:10025] Need advice on Hastelloy C22.

Hi Vijay,

 

Mr. Jayakumar mentioned the requirements of welding hastelloy C-22 in brief. The following booklet explains in details on how this alloy should be welded along with the precautions to be adopted.

 

In order to be accepted for offshore services one has to meet the requirements of NACE MR-0175,Part-3.

 

Best of luck.

 

Thanks.
