RAAJMELT-3 (AWS A5.17 F7A2-EH14)

Basic Type Agglomerated Submerged Arc Welding Flux

Classification:

AWS : SFA/A 5.17 F7A2-EH14

Characteristics:

RAAJMELT-3 is an agglomerated basic flux with very high current carrying capacity in both AC and DC. Provides excellent sub-zero impact properties and extreme resistance to cracking. Manganese behavior is neutral while slight silicon pickup occurs; therefore, use of high Mn wires (like EH14) is recommended.

Typical Applications:

Single and multi-pass welding
Structural fabrication, pressure vessels, boilers, and other medium tensile, carbon, and low alloy steel fabrications

Drying Requirement:

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