Chromium free, Nickel base metal spray powder for surfacing with the Lastispray system.
Very thin flowing and excellent bond on stainless steel, carbon steel, cast iron.
Machinable with ordinary tools.
Corrosion and oxidation resistant (good resistance against seawater).
Recommended for metal to metal wear applications.
Can also be used for joining thin cast iron pieces.
Base layer for harder metal powders on base metals that are difficult to wet.
Rebuilding worn shafts in machine repair, gears, moulds in the glass industry, bearing seatings, press tools, corrosion resistant coatings, repair of machining errors on cast iron and steel pieces.
Hardness: 190-250 HB
Fusing temperature: 1090-1120 °C (1994-2048 °F)
Density of deposit: 8,45 gr/cm³ (0.306 lb/cu.in)
The surface to be hard faced should be degreased and free of dirt. If grit blasting is used
for surface preparation all residues have to be removed by metal wire brush.
Do not touch prepared surfaces with fingers.
Preheat the work piece up to 300 °C (572 °F) and deposit a thin layer to avoid oxidation.
Heat locally up to red-hot to ensure a good bond and spray more powder to obtain the required thickness.
Spraying and melting of P902 should be done alternately.
