A ferritic stainless steel alloy useful as a substrate for catalytic converter material consists of, by weight: 15-21% Cr, 8-12% Al, 0.01-0.09% Ce, 0.02-0.1% total of REM, and possible minor amounts of further elements, other than the ones mentioned, the balance being Fe with normally occurring impurities. These alloys have managed to combine a high content of Al with a good hot and cold workability.
