“as a worldwide automobile
equipment supplier, faurecia’s
main use of stainless steels is in
exhaust systems. of the 200,000
metric tons or so of stainless
steel that we use for this purpose
annually, some 90 percent is
ferritic. in fact, we’ve been using ferritics since the mid-1970’s,
when we started producing catalytic converters conforming to
u.S. emission standards. ferritics have much lower thermal
expansion characteristics than austenitics, which was a
crucial factor in the durability of these catalytic converters.
“ferritics are a success story for us because our deep
understanding of the specific behaviour of the grades in different
exhaust environments means we can choose the right grade
for the right application. of course, formability limitations and
the need to avoid intergranular corrosion need to be taken into
account in both product design and manufacturing process.
we increasingly require continued progress with ferritics in
the areas of high temperature performance above 900°c and
corrosion resistance. we believe that such improvements to
ferritic grades will bring them closer to the performance of
austenitics, but still at a lower and more stable cost. that said,
we’re already very satisfied with ferritics.”
