AWS/ASME SFA-5.28   ER 80S-G (~ER80S-B2)

 

 

 

Application/ Properties: Medium-alloyed welding rod for TIG-Welding of Cr Mo-alloyed creep resistant boiler and pipe steels subjected to operating temperatures up to 550˚C.

 

Analysis of Wire electrode% (Typical value):

C	Si	Mn	Cr	Mo
0.1	0.6	1	1.1	0.5

Shielding gas: 100% Argon

Mechanical properties of all-weld metal  :

 

Heat treatment	Tensile Strength (N/mm2)	Yield Strength (N/mm2)	Elongation A4(%)	ISO-V Impact energy (j) 250C
T	600-700	>500	>21	>95
T+N	480-560	>350	>25	>110

T= treatment 30 min at 720C,furnace cooling to 300C

N+T= norm + treatment 30 min at 930 C, air cooling + 30 min at 720 C, furnace cooling to 300C.
