The DESULCO product range, manufactured by the US company Superior Graphite, is the leading range of recarburisers.

We are the exclusive representative of Superior Graphite’s DESULCO recarburiser for Central and Southern Europe.

DESULCOdesulphurised coke – was developed to meet the high requirements of modern metallurgy. Desulco contains up to 99.9% of carbon. It contains no dust and only a small amount of ash, and its gas levels are always low. The result is rapid adsorption, maximum carbon utilisation and minimum required dissolution time.

DESULCO will meet the strictest criteria for carburising ductible iron with maximum effectiveness.

Its extremely low gas content makes DESULCO the preferred material for treating grey cast iron and also the preferred material in steel mills producing high-quality carbon steel.
