409 Stainless Steel

UNS S40900

Type 409 has the lowest chromium content of the 400 series stainless steels. It cannot be heat-treated and because of its lower chromium content, Type 409 has lower corrosion resistance than other 400 series alloys and is not suitable for high quality appearance applications. Typical applications include automobile mufflers, casket liners, trailer bodies and swimming pool fixtures.
