NAHAVIWEL NB-EL12 Submerged Arc Welding Wire:

1.Applications:
NB-EL12 is the welding wire with low C content, average content of Mn and
 S which helps to produce welds with good base metal when used in conjunction with various welding fluxes.

2. Classifications:
Equivalent to standards:
- AWS A5.17: EL12 
- JIS Z 3351: YS-S1
Approved by Vietnam Register :
QCVN 21: 2010/BGTVT- AW3

3. Usage instructions:
NB-EL12 is suitable for all welding positions for welding
medium carbon and alloy structural steel such as: pressure tanks, bridges and roads, automobiles, ships, machineries, building structures…This can be used together with several kinds of Fluxes such as F7A(P)2,F7A(P)6 to create welds with high mechanical properties.
