Duroxite® 200 US

Download data sheet

General Product Description

Duroxite® 200 US consists of specially formulated abrasive materials deposited on mild steel backing plate that is suitable for extremely severe abrasive wear and high to moderate impact applications. The overlay material is composed of primary chromium-rich carbides and refined multiple-alloy complex carbides dispersed evenly in a ductile eutectic austenite matrix. Duroxite® 200 US is available in single and double layers.

 

Key Benefits

  • Multiple-alloy complex carbides are harder and finer than chromium carbides and interlock between the primary chromium carbides to provide better wear performance
  • Longer service life and better wear performance compared to traditional chromium carbide overlay plate

Typical Applications

Duroxite® 200 US is widely used in many industries including mining, cement, and steel. Some specific applications include:

Mining

Chutes, liner plates, conveyors sides, underground mine skips

Cement

Cement furnace components, sinter plant parts, fan blades, mixer blades, gyratory mantles, coal and cement pulverizer rolls, raw material crushing components, molding panels

Steel

Ore sintering, crushing, riddling, blast furnace hoppers, throats, and ovens

For more information on applications see the Duroxite® workshop brochure.

Tolerances

Thickness

Overlay thickness tolerance can be guaranteed within ±10% of specified thickness.

Flatness

Flatness is guaranteed over a 5 ft section of the plate. For plate sizes up to 5’ x 10’, the flatness tolerances follow the 5’ x 10’column of the tables. For wider plates (6’ x 10’or 8’ x 10’), the guarantees are as shown in the tables.

Delivery Conditions

Duroxite® 200 US is normally supplied in an as-welded condition, but can also be supplied in a ground condition upon request.

Fabrication and Other Recommendations

Welding, cutting, forming and machining

Recommendations can be found in the Duroxite® workshop brochure, or consult your local technical support representative.

Appropriate health and safety precautions must be taken when bending, welding, cutting, grinding or otherwise working on the product.

Safety precautions

When welding or cutting Duroxite® products, gases and harmful fumes are produced that are chemically complex and difficult to classify. The major toxic component in the fumes is hexavalent chromium. The proper exhaust ventilation equipment and fume-extraction torches are recommended, as well as suitable protective clothing and respiratory protection for operators.
