409 Stainless Steel Tube

Corrosion and Oxidization Resistance

To mill Type 409 Stainless Steel Tube, Phillips Tube begins with a chromium, titanium-stabilized, ferritic stainless steel. Chromium gives this steel grade its excellent corrosion resistance, making it superior to carbon steel and some coated steels.

Type 409’s corrosion and oxidation resistance extends into high air temperature environments, making it ideal for more extreme atmospheres. Good formability makes type 409 an ideal choice for hard-to-form pieces.

Thanks to the combination of elevated temperature corrosion and oxidation resistance, formability and economic cost, type 409 stainless steel tubing is a popular choice for automotive exhaust systems, including tubular manifolds; agricultural equipment such as spreaders; gas turbine exhaust silencers and heat exchangers.
