COSMOHARD – 250

Identification : Name Printed

Characteristics   :  A medium heavy coated, rutile type electrode, deposits air-hardening type weld metal of approximately 250 brinell hardness the tough overlays are highly resistant to rolling and sliding friction. The weld metal is machinable. The electrode can be operated in all conventional positions.

Applications  : Gears shafts and generals reclaimation of allworn out carbon steel parts requiring subsequent matching. For railways and tramcar rails, forging dies, wheels, axles and couplings. Pinion teeth, sprockets, tractor parts, spindles.
