ROSTFREIER CHROM-ALUMINIUM-STAHL MIT HOHER BESTAENDIGKEIT GEGEN OXYDATION UND ABBLAETTERUNG UND FOLIEN AUS CHROM-ALUMINIUM-STAHL FUER KATALYSATORTRAEGER IN KATALYTISCHEN KONVERTERN.

摘要

A high oxidation resistance Fe-Cr-Al alloy suitable for forming catalytic converter, specifically for forming an automotive catalytic convertes. The alloy is composes: C: less than or equal to 0.02 Wt%; Si: less than or equal to 1.0 Wt%; Cr: in a range greater than or equal to 14 Wt% to less than or equal to 27 Wt%; Al: in a range greater than or equal to 3.5 Wt% to less than or equal to 6.5 Wt%; La: in a range greater than 0.05 Wt% and less than or equal to 0.20 Wt%; Ce: less than or equal to 0.01 Wt%; and remaining being composed of Fe and inevitable impurities.
