Duaplate® S3 is a chromium-tungsten carbide weld overlay used for bulk materials handling applications. The manufacturing process of Duaplate®, along with the microstructure and chemical composition, gives S3 its superior properties. S3 performs well in high abrasion and high impact wear applications. Large sheets or custom shapes of Duaplate® S3 are available and can be formed into complex shapes.
An S3 microstructure consists of fine, primary M7 C 3 carbides surrounded by a eutectic mixture of carbides and austenitic matrix material. The very hard primary carbides form as hexagonal nodules and help to prevent wear of the hard-facing material. The austenitic matrix material provides mechanical support to the primary carbides whilst also helping to absorb impact.
