SPA 725 Metal spray wires




SPA 725

 
CATEGORY 
TYPE 
High-alloyed tubular wire based on a CCrMoNb alloy for thermal spray.
APPLICATIONS 
Applications that require Corrosion resistance in combination with high temperature and extreme wear.
PROPERTIES 

High wear resistance with complex carbide structure. The deposit gives a extreme high hardness and is suitable for corrosion protection, homogeneous particle distribution. The spray deposit is only machinable by grinding with diamond tools.

CLASSIFICATION
EN ISO 
14700: TFE special alloy
SUITABLE FOR 

Cement industry, pumps, mixer blades, valves seals, bearings, magnetic sensors, dimensional restoration.
