Electrodes For Weathering Steel
Mono CU
Characteristics
MONO CU is a basic coated Low hydrogen type Electrode producing
Radiographic quality Cr-Ni-Cu Alloyed Weld Metal. The deposited metal shows
high resistant to high temperature atmospheric Corrosion. Electrode is
further characterised by soft and smooth acr, easy deslagging, low spatter
and bead of excellent profile, gives deposition efficiency of above 110%.
Application
MONO CU is ideally suited for welding of highly tensile steels having
similar composition as weld metal. For Welding of dissimilar composition
steels having resistance to atmospheric corrosion as compared to Normal
steels and specially recommended for welding of weathering steels such as
CORTON steel, used in Chemical Petrochemical and in Railway Industries

Electrodes For Hard Facing
Mono Hard 300
Characteristics
MONO HARD 300 is a basic coated low hydrogen type electrode production 14%
Mn. Weld metal. The weld deposit resists high impact and gouging abrasion.
The weld surface work hardens readily by impact and pressure.
Application
Highly suitable for applications involving heavy impact and abrasion
Typical applications include crusher jaws and hammers, mineral grinder
mantles, bucket teeth and lips, rail crossing, manganese steel casting of
all types.

Mono Hard 600
Characteristics
A special heavy coated Low Hydrogen Hard Facing Electrodes, designed for
hard facing electrodes, designed for hard facing and building up of worn out
machine parts running under extremely sever conditions of impact and
abrasion. The Arc is very stable and smooth which ensure proper Alloy
Transfer to weld deposit. Weld beads are flat and smooth and the slag is
easily detachable.
Application
Surfacing and rebuilding of various parts of machine e.g. Mill hhammers
disintegrator hammers, crane wheels, cane crusher hammers, scrapper blades,
excay at or teeth, oil expeller worms, plough shares etc.
