Ferritic stainless steels with niobium can withstand the higher temperatures that are essential for optimal catalytic efficiency in modern exhaust systems. Temperatures up to 950 ºC in the manifold are fundamental for the catalytic system to convert carbon monoxide into carbon dioxide and to reduce the level of nitrogen oxide and sulfur oxide in the emissions.


Niobium helps reduce vehicle greenhouse gas emissions by making catalytic conversion more efficient.

Ferritic stainless steels with niobium are used in a variety of new applications, such as building roofs and facades, solar water heaters and potable water pipes, to name a few.
