Abstract
A system comprising a ferritic stainless steel substrate
having a tightly adherent oxide coating and a catalytic mater
ial thereupon, and the ferritic stainless steel from which the
substrate is formed. The ferritic stainless steel is of a chemis
try which forms a tightly adherent non-spalling scale suitable
for application of a catalytic bearing material and consists
essentially of, by weight, up to 26% chromium, from 1 to 8%
aluminium, between 0.01 and 0.1% yttrium, up to 0.1% car
bon, up to 2% silicon, balance essentially iron.
