X2CrTiNb18
1.4509Ti- and Nb-stabilized ferritic stainless steel with very low carbon (max 0.03%) and 17.5-18.5% Cr. The dual stabilization with Ti and Nb provides excellent resistance to intergranular corrosion and superior high-temperature oxidation resistance. Non-hardenable. Used extensively for automotive exhaust manifolds, catalytic converter housings, heat exchangers, furnace parts, and kitchen equipment. More economical than austenitic grades for high-temperature applications.
