Ferritic Nitrocarburizing (FNC) for Green Technology Components

Superior Heat Treat LLC leads in providing advanced Ferritic Nitrocarburizing (FNC) services specifically tailored for green technology components. This innovative surface hardening process is ideal for critical parts in renewable energy and sustainable applications, including hydraulic cylinders and various green energy production components. Our FNC treatment significantly improves wear resistance, fatigue strength, and corrosion resistance with minimal distortion. We’ve developed a unique FNC procedure that surpasses the stringent ISO 9277 salt spray test, achieving an exceptional 300 hours of corrosion resistance. This makes our FNC process perfect for parts exposed to harsh environments, such as those in wind energy systems. Furthermore, our low-temperature FNC process enhances wear and tear resistance (up to 70 RC equivalent surface hardness), improves part lubrication, ensures dimensional stability for finished components, and leaves parts with a sleek, durable matte graphite finish. Choose us for FNC heat treatment for green tech.
