Alloy
Shield F2S
(AWS A5.23
F10P2-ECF2-F2)
- Alloy Shield F2S wire devel-
oped for welding SAE 4130 and
similar hardenable steels. Retains excellent properties after
stress relieving or quench and tempering.
Good choice for oil field equipment requiring less
than 1% nickel. Recommended flux is
Unionmelt Flux
709-5.
If other fluxes are used, the weld metal
analysis may vary. A.
