Cobalt base welding electrode for hardfacings where maximum resistance to corrosion and wear at red heat (up to 1000 °C (1830 °F)) is required.
Excellent resistance to shocks.
Deposit machinable with hard metal tools.
Good resistance to acetic and nitric acid, and organic chemical products such as: petroleum, plastic, rubber and resins, even molten metals as aluminium and zinc.
Also used in the food and pharmaceutical industry.
Warm cutting tools, metal shear blades, stone breakers, hammers, valves and valve seats of combustion motors, glass cutting tools, shafts and pump bearings, hot working dies and moulds, ...
Hardness: 38-46 HRC
Hot hardness: approx. 31 HRC @ 600 °C (1110 °F)
Remove all rust and dirt.
Sharp edges must be rounded for optimum adhesion.
The arc should be short to avoid too much dilution with the base metal.
On crack sensitive steels, apply a buttering layer with Lastek 9066.
