Self-fluxing alloy – Nickel chromium silicon boron
55396C is mainly spherical powder manufactured by atomising a formulation of self-fluxing nickel based alloy. It has been developed for spraying with the CastoJet CJK5 system which is a High Pressure HVOF using kerosene as liquid fuel. 55396C powder is also
suitable for other HVOF systems. 55396C sprayed coatings are dense and smooth with high bond strengths on a wide variety of metallic substrates. They resist exceptionally well to corrosion, low stress abrasion, fretting and particle erosion. It can be used for service temperatures up to 800°C.
