The microstructure of Duroxite® 100 is composed of a high proportion of extremely hard primary M7C3 chromium-rich carbides with a typical hardness of 1700 HK*) dispersed evenly in a ductile eutectic austenite matrix. The volume fraction of primary carbides is maintained between 30 to 50% to provide a good combination of wear resistance and homogenous bonding.
*)HK is the Knoop microhardness used primarily for very brittle materials.
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.
Duroxite® 100 is normally supplied in an as-welded condition, but can also be supplied in a ground condition upon request.
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.
