AISI 409 ( EN 1.4512 SUH409L ) Stainless Steel Sheet Coil And Plate

Grade 409, UNS S40900 is a stabilized ferritic general purpose stainless steel with 11% chromium.

It is especially useful for applications requiring oxidation or corrosion protection beyond the capability

of carbon steel and some coated steels. 409 has good oxidation resistance and formability,

but lower corrosion resistance due to the chromium content.

409 is not as corrosion resistant as 304, 430 or 439 stainless grades, however, stainless 409 is

far superior to mild carbon steel.

409 can be formed by roll forming, stretch bending, deep drawing or pressing.

In the annealed condition 409 does not harden when cold worked using mild roll forming techniques

including pressing or stretch-bending. Welding performance for grade 409 is fair.

This stainless steel material should not be used in impact-loaded structures, because in heat affected zones

the grain structure can grow which may have a direct effect on the mechanical properties.

Typical Applications: Automotive exhaust systems applications such as manifolds exhaust pipes,

catalytic converters, mufflers, tail pipes and other components. Non-automotive exhaust applications

such as home heating systems, automotive thermostats and fuel filters, electrical transformer cases, caskets

and heat exchanger tubing.
