Jineshwar Steels is a trusted Stainless Steel 409 Pipes manufacturer, exporter, supplier, stockist, dealer, and distributor serving industrial buyers, engineering companies, fabricators, EPC contractors, and OEMs. Stainless Steel 409 is a ferritic stainless steel grade identified by UNS S40900 and is commonly selected where oxidation resistance, weldability, moderate corrosion resistance, and economical material performance are important. For tubing applications, ASTM A268/ASME SA268 is a commonly specified standard covering ferritic and martensitic stainless-steel tubing for general corrosion-resistant and high-temperature service.

As a leading manufacturer and supplier of Stainless Steel 409 Pipes, Jineshwar Steels can provide material according to project requirements covering dimensions, wall thickness, Pipes length, manufacturing route, surface condition, and applicable testing requirements. SS 409 is a chromium-containing ferritic stainless steel stabilized with titanium, making it particularly useful for applications exposed to elevated temperatures and cyclic thermal conditions. Its practical balance between material cost and performance makes it a popular choice for exhaust-related systems, heat-resistant fabrication, industrial components, and selected process applications where the environment does not demand the higher corrosion resistance of grades such as 304 or 316.

Stainless Steel 409 Pipes Latest Price List

Stainless Steel 409 Pipes is manufactured from a ferritic stainless steel alloy containing approximately 10.5–11.7% chromium, controlled carbon, manganese, silicon, phosphorus and sulfur, with titanium stabilization. Under ASTM A268 requirements, TP409 is designated UNS S40900. The chemistry is designed to provide useful resistance to oxidation and corrosion while maintaining practical fabrication and welding characteristics.

The grade is especially recognized for applications where high-temperature oxidation resistance is more important than the high general corrosion resistance expected from austenitic grades. Its ferritic structure also means Stainless Steel 409 is magnetic. When selecting a Pipes for a specific pressure, temperature, corrosion, or structural application, the purchaser should confirm the applicable product standard, dimensional requirements, design code, operating conditions, and required inspection level before ordering.

Jineshwar Steels supplies SS 409 Pipes in configurations suitable for fabrication and industrial use, subject to size and production availability. Depending on the order specification, material can be supplied with relevant heat identification, inspection documentation, dimensional verification, and test certificates.
