Nistelle™ Super C Alloy

Nistelle nickel-baed alloys are designed primarily for high corrosion resistance. They have excellent high-temperature strength, resistance to oxidizing and/or reducing acids (depending on the grade) and are readily machinable.

Nistelle Super C is a proprietary welding and thermal spray alloy that exhibits much higher resistance to oxidizing and reducing acids than Nistelle C, and offers significantly higher resistance to chloride-induced, localized attack. Nistelle Super C is also castable. Unlike Nistelle C, which has a chemical composition similar to the wrought version of the alloy, Nistelle SUPER C is specifically formulated as a powder product. It is especially useful as a corrosion-resistant HVOF coating or PTA deposit. It can be used as a corrosion-resistant thermal spray bond coat. Compared to Nistelle C, HVOF coatings of Nistelle Super C are easier to grind to a smooth finish due to the alloy’s lower tendency to work harden.
