[MW:6502] Welding of SS 304 for pressure vessel application

Dear all,


1. Why E 308 is used for welding of SS 304 instead of E 304?
2. Why E 307 is used for welding of SS 321 instead of E 321?

Of course E 321 & E 304 electrodes are not available in market.

Is there any metallurgical reason or any manufacturing difficulty?

Please give the answer with proper justification.


Regards,

Maulik H. Thakkar
Welding Engineer
