Triten Wear Resistant Overlay Steel Plate

RANGE SUMMARY

Triten manufactures a comprehensive range of wear resistant overlays for steel plates at its facilities in the USA and the UK using Triten's proprietary bulk weld process. The properties of these different overlay compositions and substrates have been engineered to provide extended service life at ambient and elevated temperatures in aggressive environments involving abrasion, erosion and impact

Triten plates are available in a range of thicknesses and choice of overlay alloy/base plate combinations produced with either single or double pass overlay layers as appropriate. Triten's particular method of manufacture of overlay plate is especially suited to producing overlay thicknesses with greatly extended service life. The narrow overlay bead morphology, and its characteristic fine pattern of stress cracking, ensures optimum resistance to the loss of the protective overlay deposit through spalling under even the most severe conditions.

Triten's proprietary plate overlay technology, combined with over fifty years of experience in the development and application of wear resistant alloys, is also available to customers to modify standard products or develop special alloys to meet specific application needs.

All Triten's wear resistant plate is manufactured under strict quality control systems approved to ISO 9002.

As part of the Company's commitment to adding value through services, Triten also offers in-house cutting and fabrication of its wear resistant plate as either liners or complete structures. In addition, Triten can provide a custom hardfacing service to protect or refurbish a wide range of wearing components with various alloy compositions.

Triten Alloy Overlays - Nominal compositions for undiluted alloy overlays

Below is a summary of Triten's alloy range showing the nominal composition of the undiluted overlay. More detailed information with compositions and hardness for single and second layer overlays is available on request.

Unless otherwise stated the typical operating temperatures of these materials is up to 840°F (450°C) although intermittent exposure to 1100 degrees F (600°C) can be tolerated. The use of a more heat resistant substrate is recommended if long periods of exposure are anticipated.
