LoTherme-600
                     LOTHERME-600
For Hard-Facing, Wear-facing or Overlay 
Applications
Co-Cr-W-alloy of Cobalt Grade 1 for surfacing 
to resist high temperature wear.
 LoTherme-600 welds well in the horizontal position. Soft arc, 
smooth seam surface. It still retains great hardness at high 
temperatures, even at red heat, and recovers its original 
hardness after cooling.
CHARACTERISTICS
 LoTherme-600 is the hardest of the cobalt-containing alloys 
and is used mainly for severe friction wear, erosion and 
corrosion. It is very resistant to sliding stressing metal-to-
metal, and is therefore recommended for pump bushes, screw 
conveyors, wear rings, guide rails, cutters, rolls.
APPLICATIONS
 AT ROOM TEMPERATURE : 45-55 HRC
 AT 600°C : 43-48 HRC
TYPICAL MECHANICAL 
PROPERTIES OF ALL WELD 
METAL
 Re-dry the electrodes at 250°C for one hour before use. Clean 
the weld zone of rust, scale and grease. Bigger work pieces 
are preheated to about 300°C. Keep the amperage as low as 
possible, so as to fuse the parent metal as little as possible. 
Guide the electrode vertically, keeping the arc short. Weave 
only slightly. Cool slowly in an oven or under asbestos. 
Machinable only by grinding.
