Specifications

Version ENG
Version RU

General description of products

Duroxite® 300 is an iron-based steel alloy deposited on a mild steel backing plate. It is designed for extremely strong sliding in both dry and wet (slurry) abrasive media. It performs well at ambient or elevated temperatures up to 1100°F (600°C). The product is available in one- and two-layer form.

Duroxite® 300 consists of specially developed abrasive materials with a uniform chemical composition of the glass-forming melt, which allows achieving high supercooling. The pad contains a unique high volume of ultrafine complex borocarbides of tungsten, niobium and molybdenum with a grain size of up to 500 nm. Borocarbides are completely moistened with a plastic matrix, which prevents premature delamination, the formation of cracks and bridges. This results in a product with a significantly improved service life that maintains high strength in cases of heavy sliding. Duroxite® 300 is an excellent alternative to Tungsten Carbide lining.

Key benefits

  • Extraordinary wear resistance in dry and wet abrasive environments with a high degree of strength.
  • Economical alternative to tungsten carbide with equivalent service life and better impact resistance.
  • The thickness of the lining is reduced compared to traditional linings, which results in lower product weight and increased service life.
  • Absorbs 25% more impact energy than a traditional chrome plate, based on continuous laboratory impact testing.
  • It has a uniform hardness throughout the thickness from 67 to 70 HRC for single and multi-layer application. Retains a high hardness of approximately 60 HRC after exposure to high temperatures up to 1100°F (600°C).
  • Retains constant wear resistance from the surface to 75% of the lining.

Typical programs

Duroxite® 300 is suitable for use in mining, cement, oil sands, steel, power generation, agriculture, oil and gas, and construction. Below are some typical applications:

 

Mining Sieve plates, loader bucket liners, ball mill feed systems, liners loader buckets, bucket edge covers, bucket side covers, chutes, liner plates and skip liners

Microstructure

The Duroxite® 300 coating contains an ultrafine complex borocarbide phase down to approximately 500 nm in a plastic matrix. A typical volume fraction of borocarbides is maintained between 60 and 70% to form a homogeneous solid matrix. SEM (Scanning Electron Microscopy) / EDS (Energy Dispersive Spectrometry) analysis of the Duroxite® 300 coating confirms that the purified borocarbides are tungsten, niobium, molybdenum, and chromium rich borocarbides dispersed in an iron-based matrix. Ultrafine borocarbides are approximately 200 times smaller than traditional chromium carbides.

General description of products

Duroxite® 500 is a welded iron-based steel alloy deposited on a mild steel backing plate. It is designed for a good combination of sliding wear and high impact for both dry and wet (slurry) abrasive media. It performs well at ambient or elevated temperatures up to 1100 °F (600 °C). The product is available in one- and two-layer form.

Duroxite® 500 consists of specially developed abrasive materials with a homogeneous glass-forming melt chemistry that allows for high supercooling. The pad contains a unique ultra-fine borocarbide phase, enriched with chromium and niobium, with a grain size reduced to 500 nm. Borocarbides are completely moistened with a plastic matrix, which prevents premature delamination, the formation of cracks and bridges.

1) Surface hardness is measured on a machined flat surface just below the overlay surface.

2) ASTM G65 – Weight Loss Procedure A is a standard test for measuring sliding abrasion resistance using a dry sand/rubber wheel apparatus. ASTM G65-Procedure A is the most stringent test method.

3)  ASTM G65 – Weight Loss Test Procedure, wear is carried out at 75% of the depth of overlay materials to ensure consistently good wear resistance from the top surface to the depth of 75% of the overlay.

Microstructure

The Duroxite® 500 coating contains an ultrafine complex borocarbide phase down to approximately 500 nm in a plastic matrix. A typical volume fraction of borocarbides is maintained between 60 and 70% to form a homogeneous solid matrix. SEM (scanning electron microscopy) / EDS (energy dispersive spectrometry) analysis of the Duroxite® 500 coating confirms that the refined borocarbides are niobium-rich borocarbides and chromium-rich borocarbides dispersed in an iron-based matrix. Ultrafine borocarbides are approximately 200 times smaller than traditional chromium carbides.

Tolerances

Thickness

Tolerances on total and overlay thickness can be guaranteed within ±10% of the specified thickness.

flatness

Plate flatness tolerance can be guaranteed to within ±3 mm (±1/8”) per 1.5 m (5′) of plate length for plate sizes equal to or less than 1.5 m (5′) x 3, 0 m (10′). For plates greater than 1.5 m (5′) wide and 3.0 m (10′) long, a flatness tolerance of ±25 mm (±1”) can be guaranteed.

Manufacturing and other recommendations

Welding, cutting, forming and machining

Refer to the Duroxite® product brochure for recommendations or contact your local technical support representative for more information.

Safety equipment

When welding or cutting Duroxite® products, fumes are generated containing harmful vapors and gases that are extremely complex in chemistry and difficult to classify easily. The main toxic component in the fumes and gases produced in the process is hexavalent chromium. Adequate exhaust ventilation equipment and fume extraction flares are recommended, as well as suitable protective clothing and respiratory protection for operators.
