Basicity Index (B.I.) : 3.20
Grain Size : 10 X 60 BSS (0.25-1.60 mm)
Density : ~1.1 kg/dm³

Characteristics:

Raajmelt-B62 is a Fluoride-Basic flux suitable for high strength fine grain structural steels, cryogenic steels, and steels resistant to aging. It exhibits neutral metallurgical behavior, providing proper pick-up and burn-out of Si and Mn, and is compatible with almost every wire electrode.

Typical Applications:

Suitable for tandem and multi-wire welding
Welding offshore compounds
General structural steels, pressure vessels, pipe steels, and fine grain steels

Drying Requirement:

Redrying recommended at 350°C for 2 hours before use.
