Product Overview

What are SS 409 Coils or AISI 409 Coils?

SS 409 Coils are stainless steel ferritic coils, mostly made of chromium and stabilized by titanium. This grade provides high oxidation resistance, superior shapeability, and cost efficiency. The ferritic structure offers protection against thermal fatigue and oxidation at high temperatures, while Titanium stabilization helps prevent intergranular corrosion when welding, ensuring weld and dimensional stability in hot environments.

Frequently Asked Questions

Quick answers about Stainless Steel 409 Coils / AISI 409 Coils.

SS 409 coils are primarily used in automotive exhaust systems, mufflers, catalytic converters, and other applications requiring heat and oxidation resistance at an economical cost.
They are preferred due to their good high-temperature oxidation resistance, weldability, and cost-effectiveness compared to austenitic stainless steels.
SS 409 coils are manufactured through hot rolling or cold rolling processes followed by annealing and pickling to enhance strength, surface finish, and corrosion resistance.
Yes, they are suitable for components exposed to mild corrosive and high-temperature environments, such as heat exchangers and tubing systems.
Thicker SS 409 Coils use more material and require more energy to process, increasing weight-based production and logistics costs.
Yes. Wider or non-standard SS 409 Coils increase material usage and may need additional slitting or specialized handling, raising the final price.
Improved finishes like pickled, bright, or coated involve extra processing and inspection stages, which increases the total cost.
Prices follow trends in iron, chromium, and nickel scrap; any increase in these raw material costs directly raises the global coil prices.
