Stainless Steel 409 Foil

Stainless Steel 409 foil is a ferritic stainless steel that offers acceptable corrosion and oxidation resistance in high-temperature applications. It is mostly applied in automotive and industrial applications where high mechanical properties and, at the same time, low cost are desired. This alloy contains chromium as the main strengthening element, which gives it corrosion resistance and a slightly lower nickel content.

Advantages of Stainless Steel 409 foil

These flexible foil fittings offer numerous benefits for various industrial applications.

Cost-Effective: It is cheaper than austenitic stainless steel since it has less nickel than the Stainless Steel 409 foil. This makes it suitable to be used in areas that require a lot of consideration on the amount of money to be spent.
Excellent Fabricability: Stainless Steel 409 can be rolled into thin foils, and used in applications where flexibility and strength are desirable.
Magnetic Properties: Stainless Steel 409 foil is magnetic while austenitic grades are not, depending on the use this may be a bonus.
Low Maintenance: Stainless Steel 409 foil has good oxidation and corrosion resistance thus it does not need frequent maintenance which may in the long run cut down on costs.
Recyclability: Sustainable as the product is made from recycled material and is recyclable to the last bit of it.

Stainless Steel 409 foil offers several advantages that make it suitable for industrial and commercial applications.

Common Applications of Stainless Steel 409 foil

Due to its excellent features, the Stainless Steel 409 foil is preferred in various industrial applications. Some of the main applications include.
