Dear All,
Thank you for the valuable inputs.
Construction codes: ASME B31.3 and welding code ASME SEC IX
I want to weld ASTM A 790(UNS 32750) to ASTM A 790(UNS32750), ASTM A 928(UNS32750) to ASTM 928 (ASTM32750).Then ASTM ASTM A 790(UNS 32750) to ASTM A 928(UNS32750).What electrode and filler wire I have to select? Normally at what direction impact test doing on weld metal, ie, transverse or longitudinal or both direction? From where I can get the minimum charpy value required on impact test? I have reviewed ASTM standards, found minimum tensile and yield strength values, but couldn't find any minimum required impact value.
Regards,
Limesh

Dear All,
What is the difference between Duplex and super duplex stainless

What is the P. No for duplex and super duplex stainless steel?
One of our duplex stainless steel PQR failed in impact test.What would
be the reason?
Thanks and Regards,
