Dur 71 SMAW Stick Electrodes




Dur 71

 
TYPE 
Basic coated electrode with a sintered tungsten carbide core wire.
APPLICATIONS 
For extreme wear resistance, elements as Niobium and Chromium carbides are also added to obtain a complex carbide structure. Specially used for applications subject to abrasive wear such as sand or other minerals with little impact. Recommended for the brick and clay industry or extreme high temperature applications in power plant industries.
PROPERTIES 

Ceweld Dur 71 is designed to offer full wear resistance and high hardness already achieved in the first layer. To be welded with low as possible current to avoid burnout of elements.
