Duroxite 400

Duroxite® 400 is a specially formulated hardfacing overlay pin engineered and designed to withstand severe heat and metal-to-metal wear applications.

Its exceptional quality comes from the precise control and selection of raw materials as well as proprietary processing. The maximum working temperature for the product is 480 °C (900 °F). The work-hardening hardness of the Duroxite® overlay pin can reach up to 58 HRC in service. The Duroxite® 400 overlay pin matches with 12% Manganese Bushings. This Bearing System is expected to last longer than traditional hardened surfaces used such as induction heated and quenched 4140 pins.

Key benefits

  • Provides superior wear resistance in overlay and a tough inner core
  • Performs well when torqueing and surface compression are involved
  • Matches with 12% manganese bushings with bearing system lasting longer than traditional hardened surfaces such as induction hardened 1040 and 4140 pins
  • Designed to outlast original equipment and manganese pins by 3:1

Typical Applications

Duroxite® 400 was originally developed for dragline bucket components but has gained wide acceptance in other applications as well. It is also used for heavy mining or industrial equipment, such as dragline shovels, clam shell buckets, sheave pins, backhoe pins, and crusher shafts.

Overlay pins can be machined to meet the requirements of any specific application.
