Submerged arc welding wire
Field of Apply
- NB-EL12 is the welding wire with low C, Si content, average Mn and very low content of S and P which is able to welds with good base of metal. This can be used together with several kinds of Fluxes such as F7A(P)2,F7A(P)6...to create high mechanical properties welds as expected.
- NB-EL12 is suitable for welding structure of the carbon and low-alloy steel such as : tanks, bridge and road, automoblie, ship, machinery, building structures…
