RAAJMELT-SS (DIN 32 522)

General Purpose Stainless Steel Submerged Arc Welding Flux

Classification:

DIN : 32 522
Basicity Index (B.I.) : 1.20
Grain Size : 8 x 60 BSS

Characteristics:

Raajmelt-SS is a special basic welding flux used for welding stainless steels and heat-resistant steels with AWS/SFA 5.9 wire electrodes. The flux is neutral, ensuring minimal loss of chromium and allowing welding of low carbon steels when using the correct wires. Its metallurgical behavior with respect to silicon and manganese is neutral.

Typical Applications:

Joint welding on high alloy Cr-Ni steels such as AISI 304, 304L, 316, 316L, 347, 321, 318, 410, 430, etc.

Drying Requirement:

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