Product Description

Floppy Rod For Utmost Abrasion Resistance (also available in electrode)

ASTRO 999-A1 is a new concept in hardfacing, utilising tungsten carbides in spherical matrices such that they have the approximate hardness of diamond.

 

GENERAL CHARACTERISTICS:

In our unique, flexible ASTRO 999-A1 consumable, crushed or spherical carbides surround a small diameter nickel core wire and are set in a high grade nickel alloy matrix and binder.  The dense, wear resistant properties of the finished surfacing are assured, by maintaining both the ratio and combination of carbide sizes throughout the length of the rod.

 

TYPICAL APPLICATIONS:

ASTRO’s tungsten carbide 999-A1 can be used under the most severe conditions in many industries to achieve longer life against abrasion, less down time and to serve as a protective surface which can be rebuilt again and again when necessary.

 

FEATURES:

  • Reduced distortion and oxidation of base metal
  • Dense distribution of carbide particles
  • Continuous solid, but flexible
  • Corrosion resistant matrix
  • Faster coverage rates
  • Easy repairs

 

OIL INDUSTRY:

On stabilisers, drill strings, bits and finishing tools

 

DREDGING:

On cutter teeth, dragging teeth and pump castings

 

CEMENT AND BRICK:

On augers, extruder and feed screws, deflection cones, pump rings and liners

 

ALLOY AND STEEL FOUNDRIES:

On sand and coal mixer paddles, guides and raking equipment

 

PAPER:

On mixers, compression screws, pulverisers and shredders

 

MINING AND POWER:

Between coal crusher teeth, on rotating bucket teeth, and pulverised fuel system

 

CLAY AND CERAMICS:

On wetting and mixing units, grinding cylinder scrapers, rakes and crusher teeth

 

PLASTICS AND RUBBER:

On mixer/extrustion screws and liners, rotors and spares

 

OXY WELDING PROCEDURES:

As with all surfacing products, the removal of any scale, rust or oxidation from the base material by machining or grinding is essential.

Use a nozzle at least one size larger than usual for fusion welding the thickness of metal.

Use a flame with an excess of acetylene.

Do NOT melt the base metal, it should only ‘sweat’.

Do NOT stir the molten pool, otherwise the hard particles will sink and the surface will become too soft.

The thickness of each layer should not exceed 3mm. (maximum 2 layers, 6mm).
