Stainless Steel 316 Pipe Manufacturer, Supplier & Exporter in India — Nishra Overseas
Nishra Overseas is a leading Stainless Steel 316 Pipe manufacturer in India, and a dependable 316 Pipe supplier and exporter in India, serving marine, chemical processing, pulp and paper, and general industrial buyers across domestic and international markets. Whether you're sourcing Stainless Steel 316 Pipe in India for a single project or for ongoing supply, our stock depth and manufacturing capability are built to support both.
316 is a standard molybdenum-bearing austenitic grade, and the molybdenum content is what sets it apart from 304: it gives 316 markedly better resistance to pitting and crevice corrosion, particularly in chloride-rich environments. Stainless Steel 316 pipe carries a minimum tensile strength of 515 MPa and a minimum yield strength of 205 MPa, with a density of around 8000 kg/m³ and elongation of up to 40%. Because it holds up so well in saline and marine conditions, 316 is often referred to simply as "marine-grade" stainless steel, and it remains reliable at operating temperatures approaching 1400°C at the material's melting point.
Seamless 316 pipe — drawn from a single piece of steel with no fillet or weld seam — is generally the stronger option and is available from roughly ½" up to 24" in outer diameter, while welded (ERW/fusion-welded) 316 pipe extends the size range further, up to 100" in some fusion-welded forms. Both forms are widely used in marine systems, pulp and paper processing, and chemical plant piping. As a trusted Stainless Steel 316 Pipe manufacturer, supplier, and exporter in India, Nishra Overseas' goal is straightforward: deliver certified, high-quality 316 pipe and tube at fair, competitive pricing, backed by dependable stock availability.
