High-performance stainless steel 409 pipes from Vinit Stainless, a reputable manufacturer and supplier in Chennai, India, are made to last and be cost-effective in conditions that are both mildly corrosive and hot. Because of its exceptional weldability and strong resistance to oxidation and corrosion, ferritic stainless steel SS 409 is a popular choice for industrial and automotive applications. Vinit Stainless guarantees that all 409 pipes are available in a range of sizes, wall thicknesses, and finishes and satisfy international quality standards. Exhaust systems, heat exchangers, and structural applications where strength and heat resistance are essential frequently use our SS 409 pipes.
With trace amounts of carbon (maximum 0.08%), manganese, silicon, and titanium for stabilisation, stainless steel 409 pipes normally contain 10.5–11.75% chromium. Although heat treatment cannot harden this ferritic alloy, it has good formability and a moderate resistance to corrosion. A yield strength of roughly 170 MPa and a tensile strength of 380–620 MPa are provided by SS 409 pipes. Up to 675°C, the alloy resists oxidation and functions well at moderate temperatures. It is a sensible option for high-temperature structural and exhaust-related applications due to its enhanced weldability and affordability.
