For applications needing exceptional resistance to high temperatures and intergranular corrosion, Vinit Stainless, a reputable manufacturer and supplier in Chennai, India, provides premium stainless steel 321 coils. Austenitic stainless steel stabilised with titanium, SS 321 was created especially for applications involving extended heat exposure. Vinit Stainless makes sure that our 321 coils are produced in accordance with international quality standards by utilising cutting-edge processes and premium materials. These coils are perfect for heat exchangers, furnace components, and exhaust systems in sectors like petrochemical, aerospace, and thermal processing because they come in a range of thicknesses, widths, and finishes.
In order to stabilise the alloy against carbide precipitation, stainless steel 321 coils usually have 17–19% chromium, 9–12% nickel, and titanium added in amounts at least five times the carbon content. After welding, this stabilisation enables the material to withstand intergranular corrosion. SS 321 has a yield strength of roughly 205 MPa and a tensile strength of 515–750 MPa. At high temperatures (up to 870°C), the alloy maintains good strength and ductility while providing exceptional resistance to oxidation. Because of its mechanical qualities, it is perfect for welded and high-temperature structural applications without sacrificing corrosion resistance.
