| No-Problem Abrasion Resistance Even for Thicker
Plates |
| A high alloyed basic hardfacing electrode depositing
a non machinable air-hardening weld metal. The weld
deposit is resistant to severe abrasion and moderate
impact between metal to mineral wearing stresses. It
also resists scaling upto temperatures around 300°C
and also moderate corrosion. |
| |
| Apart from applications on mild and medium carbon
steels Duroid 6508, being basic coated, can also be
used over high carbon and alloy steel base metals and
on jobs of thicker cross-section. Requirement of preheat
can be lowered or avoided altogether to obtain weld
deposit free from cracks, porosity and slag inclusions
when normal welding practice for basic coated electrode
is followed. |

| ALLOY BASE |
| Fe, Cr, Mn, Mo, V |
| |
| SPECIAL FEATURES |
- Can be used on thicker sections without the need of
buffering
- Smooth arc with low spatter
- It is very ea$y to use in all positions. Excellent weld
bead appearance
|
| APPLICATIONS |
| Coal cutter blades, rock drills, drill bits, oil expeller
worms, cane & bamboo cutting knives, excavator teeth,
hot & cold punching dies, bucket lips, dipper teeth,
impellers, muller ploughs, chutes, conveyors, shears &
croppers, pulping knives, ploughshares, road graders,
crusher hammers, caterpillar treads & shoes, etc. This
electrode is specially recommended for applications
involving metal to mineral wear. |
