Stainless Steel Type 409、409 Ultra Form

Type 409 (UNS S40920)
Description
Type 409 is a heat resisting ferritic stainless steel providing good oxidation and corrosion resistance compared to carbon steel. This titanium stabilized grade was developed for automotive exhaust systems but its good formability, weldability, and corrosion resistance has led to its use in other applications. The corrosion resistance of Type 409 is better than coated carbon steel, similar to that of Type 410 stainless steel, and less than that of Type 304/304L stainless steel. Type 409 is not suggested for cosmetic or surface critical applications as light surface rusting can form during exposure to atmospheric conditions.

Type 409 ULTRA FORM® (UNS S40920)
Description
Type 409 Ultra Form is a heat resisting ferritic stainless steel providing better  oxidation and corrosion resistance compared to conventional Type 409 stainless steel.  This grade also has enhanced formability compared to Type 409 stainless steel and can be used to fabricate more complex shapes.  The corrosion resistance of Type 409 Ultra Form is better than coated carbon steel and Type 410 stainless steel, but less than that of Type 304/304L stainless steel.
