                                                DUROXITE®  500

                                                YOUR SOLUTION FOR WEAR AND HIGH IMPACT



                                                Duroxite®  500 is the latest addition to the range of Duroxite® overlay products. It is designed for applications involving abrasive wear and high impact in dry and wet environments. Duroxite® 500 can replace cast materials, titanium carbide overlay products or ceramic materials.

                                                 
                                                Duroxite(R) Formula

                                                Ultra-fine complex borocarbides stand up to impact

                                                Duroxite® 500 overlay contains complex borocarbides that are 200 times finer than chromium carbides. The complex borocarbides prevent spalling and cracking when exposed to high impact.
                                                Duroxite(R) longer life

                                                3 times longer wear life in copper mine

                                                When replacing the cast Mn liner plate with Duroxite® 500 in the belt machine head, wear life increased from 15 to 45 days. 2,700,000 tons of copper ore was processed before maintenance compared to 900,000 tons for the cast liner.
                                                Duroxite(R) hardness at high temperature

                                                High hardness also at high temperature

                                                Duroxite® 500 has a uniform through-thickness hardness of 67 to 70 HRC for single and multiple-layer overlays. It maintains a high hardness of approximately 60 HRC after exposure to temperatures up to 600°C (1100 °F).

                                                2) ASTM G65 is a standard test measuring sliding abrasion resistance using a dry sand/rubber wheel apparatus. ASTM G65-Procedure A is the most severe test method.
                                                3) ASTM G65 wear test is conducted at 75% depth of the overlay materials to ensure consistently good wear resistance from the top surface through
                                                to the depth of 75% of the overlay.


                                                Duroxite® 500 overlay contains an ultra-fine complex borocarbide phase down to approximately 500 nm in a ductile matrix. The typical volume fraction of borocarbides is maintained between 60 to 70% to form a uni-form hard matrix. The SEM (Scanning Electron Microscopy) / EDS (Energy Dispersive Spectrometry) analysis of the Duroxite® 500 overlay confirms that the refined borocarbides are niobium-rich borocarbides, and chromium-rich boro carbides dispersed in an iron-based matrix. The ultra-fine borocarbides are approximately 200 times finer than the traditional chromium carbides.


                                                Thickness

                                                Overall and overlay thickness tolerances can be guaranteed within ±10% of specified thickness.

                                                Flatness

                                                Plate flatness tolerance can be guaranteed within ±3 mm (±1/8”) over 1.5 m (5’) plate length for plate dimensions equal to or less than 1.5 m (5’) x 3.0 m (10’). For plates greater than 1.5 m (5’) wide by 3.0 m (10’) long, the plate flatness tolerance can be guaranteed within ±25 mm (±1”).

                                                Duroxite® 500 is supplied in an as-welded condition.
