General Product Description

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
  • Designed to outlast original equipment and manganese pins

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.
