Ferritic Grade JIS G4312 SUH409L Stainless Steel Sheets And Plates
Ferritic stainless steels are classified in the 400 series, usually with 10% to 30% chromium content,
and are often chosen for their excellent corrosion resistance and elevated temperature oxidation resistance.
With greater strength than carbon steels, ferritics provide an advantage in many applications where thinner
materials and reduced weight are necessary, such as automotive emission control systems.
They are nonhardenable by heat treating and are always magnetic.
Typical applications for ferritic stainless steels include petrochemical, automotive exhaust systems and trim,
heat exchangers, furnaces, appliances and food equipment to name a few.
409L is a low cost ferritic stainless steel.
Its dominant use is in vehicle exhaust systems, so much so that it is often referred to as “muffler” grade.

TYPE 409 STAINLESS STEEL is especially useful for applications requiring oxidation or
corrosion protection beyond the capability of carbon steel and some coated steels.
Current uses include automotive and truck exhaust systems, tubular manifolds, agricultural spreaders,
gas turbine exhaust silencers, heat exchangers and fuel filters.
This alloy provides good oxidation and corrosion resistance for automotive and non-automotive exhaust applications.
409 Stainless grade combines the following characteristics:
- Basic corrosion and oxidation resistance
- Composition balanced for optimum formability
- Weldable only in thin sections due to fully ferritic structure
- Low cost and limited cost variation due to low alloy content
Other applications include:
Heat exchangers, gas boilers, fuel filters.
