Description

A break through in matrix formulation designed to combat extreme abrasion

Procus 240 is an alloy formulation that provides a low application temperature to minimise dilution so as to maximise resistance to extreme abrasion.

• a special matrix formulation which maximises resistance to abrasion.
•  its low running temperature characteristics ensures minimum dilution of the base metal.
• superb for use on components subjected to high stress abrasion.
• alloy has excellent ac – dc current characteristics.

Procus 240 is the most cost effective alloy to combat extreme abrasion.

A matrix formulation of tungsten and chromium carbides to provide maximum resistance to extreme abrasion.

The high operating current required for ordinary hardfacing rods can have many detrimental effects on the job at hand but, generally, the major effect is that of substantially reduced resistance to wear.

The higher the operating temperatures required for those rods, the higher the rate of dilution and the potential for the destruction of some of the carbides. The high amps will destroy carbides, particularly the secondary carbides, and also assist the migration of both the primary and secondary carbides into the base metal where no useful purpose is served. The effect is that there would be less carbides in the deposited material, where they are required, to maximise resistance against wear.

Procus 240 has some unique characteristics. Its low amps required to run the electrode means that less dilution of the base metal material will occur. This means that an infinitely greater percentage of the carbides remain in the deposited material.

The result is that a more consistent hardness of the deposited material to ensure that the wear of the deposit is constant through its entire depth, reducing the incidence of localised wear. The unique carbide matrix formulation of procus 240, combined with a precise but limited quantity of virgin tungsten carbides, produces an electrode which gives maximum resistance to extreme abrasion, like that experienced in the mining and quarrying industries, at a cost effective price.

Because of the extreme abrasion resistance provided by procus 240, the alloy will provide excellent service to components subjected to high stress abrasion but moderate impact.
