Ferritic AISI 439 EN 1.4510 Cold Rolled Stainless Steel Sheet And Strip Coil
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.
