Ferritic AISI 439 EN 1.4510 Cold Rolled Stainless Steel Sheet And
Strip Coil
Oxidation resistance and corrosion resistance superior to Type 409
make Stainless Steel 439
attractive for numerous automotive exhaust applications.
Suggested applications include tubular manifolds and other exhaust
system areas where
temperatures may exceed the oxidation limit of Type 409 or where
aqueous corrosion resistance,
particularly to chlorides, is needed. Steel 439 is a ferritic
stainless steel that outperforms Type 409
in both oxidation resistance and corrosion resistance.
Special adjustment to chemical composition combined with special
processing give this alloy excellent
formability that is reproducible, coil after coil and heat after
heat.
This provides special advantages when producing difficult-to-form
exhaust system components.
