| Description
and Applications |
| An agglomerated
neutral flux for submerged arc welding. SUBTECH-AB |
| 18 is specially
developed for single or multipass butt welding and fillet |
| welding
of structural steels, pipe steels, ship steels and high tensile |
| strength
steels having a yield strength up to 430 N/mm² . |
| SUBTECH-AB
18 has excellent operating characteristics and produces good |
| impact properties
when used with S1 or S2Mo wires. It provides pores free |
| welds and
good appearance weld beads, easy removable slag. |
