D90 Microstructure at 100x magnification Typical D90 finish Duaplate D90 cement meal duct Duaplate D90 Flyer ©2008 BRADKEN ® BRADKEN Base Material 12 PRODUCTS Duaplate is a clad plate manufactured by welding an abrasion resistant material to a steel base. The standard base material is mild steel; however, this can be changed to suit your operating environment. Overlay Material The D90 overlay material is a martensitic chromium carbide iron that is based on AS2576-2560. The microstructure of this material consists of primary M 7C 3 carbides in a carbide martensite eutectic matrix. The material is resistant to fine particle abrasion due to the improved hardness of the matrix. Typical Properties Bulk Hardness: 700HV50 Typical Carbide Hardness: 1500 HV0.5 Volume Fraction Primary Carbides: 30% Welding Duaplate ® D90 The base material can be welded with standard mild steel or low hydrogen welding consumables with no pre-heating required. However, care should be taken to avoid contacting the overlay material.

It is preferable to cut Duaplate from the backing plate side to ensure a clean edge and to prevent carbide contamination. Duaplate can also be easily cold formed into almost any shape that mild steel can, by pinch rolls or hydraulic press brake. The steel backing plate provides Duaplate with structural integrity, thus entire structures can be fabricated from Duaplate. <strong>Bradken</strong> has the capabilities to manufacture such structures or to supply cut and formed, ready-to-go wear liners. Services & Applications Duaplate D90 is suited for severe sliding abrasion or fine particle abrasion with low impact. Typical uses include: � �� Duaplate ® D90 Cement chutes Cyclones Fan blades Fan casings Agricultural implements Trommel screen liners Sizing Screens For more information contact <strong>Bradken</strong> at wpbsales@bradken.com.au 170 Railway Parade Bassendean WA 6054 Australia T +61 8 9449 8300 F +61 8 9449 8334 W bradken.com.au
