Are you in search of a reliable Stainless Steel 409 Tube supplier? Look no further than Amardeep, a trusted
and leading manufacturer and supplier of Stainless Steel 409 Tubes. Our extensive range includes various
sizes, surface treatments, and products compliant with ASTM standards. We take pride in offering top-quality
SS 409 Tubes, a popular choice for automotive exhaust systems, including tubular manifolds, as well as
agricultural equipment.
Stainless Steel 409 Tubes, also known as UNS S40900 Tubes, are composed of chromium and titanium-stabilized
ferritic stainless steel. The presence of chromium imparts excellent corrosion resistance to this steel grade,
surpassing that of carbon steel and some coated steels.
Ideal for applications requiring superior oxidation or corrosion protection beyond the capabilities of carbon
steel and certain coated steels, Stainless Steel 409 Seamless Tubes stand out. Despite being a Ferritic steel,
Stainless Steel 409 Welded Tubes are renowned for their exceptional mechanical properties, which far exceed
their physical appearance.
Explore our range of Stainless Steel 409 Cold Drawn Tubes and SS 409 Electropolished Tubes, known for their
improved formability. Widely used globally, these tubes offer high performance, a beautiful surface, and
excellent dimension accuracy. Contact us today to request a competitive quote for Grade 409 tubes or any other
stainless steel tubes. We're here to assist you!
