FusoFlex

Nichromang:

Versatile basic coated austenitic steel electrode, with core wire of 18-8 stainless steel.
Easy to operate in all positions, except vertical top to bottom
Low spatter
Relatively easy slag detachability, considering the highly basic nature of slag
Beads of regular profile, but slightly convex

Identification:Name Printed

Applications:Weld metal of excellent resistance to scaling upto 850°C. Suitable for joining of austenitic steels with ferritic steels, & such combination is good for service temperature upto 550°C

Carbon or low-alloy steels;
Plain chrome stainless steels:
Antimagnetic steels;
High carbon & heat treated steels, including armour steels.
Remarkably low sensitivity to cracking, which enables it to withstand high welding stresses developed in rigid structures.
Also high degree of formability.

Notes on usage:

Redry electrodes for 30 minutes at 200-250°C;
Use short arc;
Avoid large molten pool;
Normally no preheating need be employed;
For thick & hard enable materials, preheating to 200-250°C recommended;
For austenitic manganese steels, avoid preheating & keep heat input as low as possible through staggered beads and/or intermediate cooling;
As core wire is of austenitic stainless steel, avoid using currents higher than necessary.
