For Hard-Facing, Wear-facing or Overlay Applications

LoTherme-606

Co-Cr-W-alloy of Cobalt Grade 6 hard-facing to resisting impact and wear. 

Characteristics

LoTherme-606 welds well in the horizontal position. Soft arc, smooth seam surface. High resistance to impact, corrosion and hardness at elevated temperature under alternating temperatures stressing.

Applications

LoTherme-606 is used primarily on work-pieces exposed to high alternating temperatures and corrosion. Specific applications: valves and valve seats, sealing surfaces, hot shear blades, hot pressing tools, forging de-burrers, wire mill rolls and beaters for coke combustion.

Typical Mechanical Properties Of All Weld Metal

AT ROOM TEMPERATURE : 32-40 HRC

AT 600°C : 30-35 HRC

Welding Instructions

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 with tungsten carbide tools.
