Mechanical Properties
2) ASTM G65 - Procedure A weight loss, 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.
Microstructure
The microstructure of Duroxite® 200 contains primary chromium-rich carbides and refined multiple-alloy complex carbides with a typical hardness of 2500 to 3000 HK *) dispersed evenly in a ductile eutectic austenite matrix. The typical volume fraction of primary chromium-rich carbides is maintained between 30 to 40% with 7 to 10% of multi-alloy complex carbides.
*) HK is the Knoop microhardness used primarily for very brittle materials or thin sheets.
Thickness
Tolerances according to Duroxite® Thickness Guarantee.
Duroxite® 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 following flatness guarantees apply.
For custom sizes, please consult your local sales representative or Hardox Wearparts center for flatness guarantees.
Delivery Conditions
Duroxite® 200 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® Product brochure, or consult your local technical support representative.
Bendability for Duroxite® overlay plate are according to Duroxite® Bending Guarantees.
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.
