SS 409L Flat

SS 409L flat bar is made of stainless steel 409 grade which is a general purpose, chromium, titanium stabilized, ferritic stainless steel whose primary application is automotive exhaust systems. SS 409L flat bar contains 11% chromium which gives the stainless steels their resistance to corrosion to form the passive surface film.

SS 409L flat bar combines' good elevated temperature corrosion resistance with medium strength, good formability, and overall cost. SS 409L flat bar is commonly used in applications where appearance is a secondary quality to mechanical properties and corrosion resistance.

Amanat Steels is one of the major manufacturers of SS 409L flat bar. We produce high quality SS 409L flat bar. Our SS 409L flat bars are in compliance with best of industry standards. Because of our strict quality control mechanism our produced SS 409L flat bars are unmatchable in the market.
