RAAJMELT-1 (AWS A 5.17 F7A0-EL8)

Alumina-Silicate Type Agglomerated Submerged Arc Welding Flux

Classification:

AWS : SFA/A 5.17, F7A0-EL8
Basicity Index (B.I.) : 0.80
Grain Size : 8 x 60 BSS

Characteristics:

Raajmelt-1 is a submerged arc welding (SAW) flux suitable for welding mild steel and medium tensile steels. Provides x-ray quality welds with smooth and shiny weld beads. Slag is auto-removable even during root runs, ensuring consistent weld quality.

Typical Applications:

Structural fabrication, offshore platforms, shipbuilding
Pressure vessels and boilers involving mild and medium tensile steels
Machine building, automobiles, locomotives, earthmoving equipment
LPG cylinders, penstocks, and similar industrial applications

Drying Requirement:

Redrying recommended at 250-300°C for one hour before use.
