Stainless Steel 316L Pipe Manufacturer, Supplier & Exporter in India — Nishra Overseas

Nishra Overseas is a leading Stainless Steel 316L Pipe manufacturer in India, and a dependable 316L Pipe supplier and exporter in India, serving marine, chemical processing, pharmaceutical, and welded-fabrication buyers across domestic and international markets. Whether you're sourcing Stainless Steel 316L Pipe in India for a single project or for ongoing supply, our stock depth and manufacturing capability are built to support both.

316L is the low-carbon version of 316, carrying the same chromium-nickel-molybdenum backbone but with carbon capped at a much lower level. That single change matters more than it sounds: lower carbon means far less risk of carbide precipitation at the heat-affected zone during welding, so 316L holds onto its corrosion resistance after fabrication instead of becoming vulnerable to sensitization the way higher-carbon grades can. Per ASTM A312, Stainless Steel 316L pipe carries a minimum tensile strength of around 485 MPa and a minimum yield strength of around 170 MPa, with roughly 40% elongation and a density near 8000 kg/m³ — figures worth confirming against your specific mill certificate, since exact minimums can shift slightly by product form and heat.

Like standard 316, the molybdenum content gives 316L strong resistance to pitting and crevice corrosion in chloride-rich and marine environments. Its austenitic structure also performs well down to cryogenic temperatures, which — combined with its excellent weldability — makes 316L a common choice wherever a pipe will be welded in the field and then exposed to demanding chemical or marine service: heat exchangers, dyeing equipment, pharmaceutical piping, and general process lines. As a trusted Stainless Steel 316L Pipe manufacturer, supplier, and exporter in India, Nishra Overseas' goal is straightforward: deliver certified, high-quality 316L pipe and tube at fair, competitive pricing, backed by dependable stock availability.

Technical Reference Data

Chemical Composition (%)

Grade	C (max)	Mn (max)	Si (max)	P (max)	S (max)	Cr	Mo	Ni	N (max)
316L	0.03	2.0	0.75	0.045	0.03	16.0–18.0	2.0–3.0	10.0–14.0	0.10

The defining difference from standard 316 is the carbon ceiling — 0.03% max for 316L versus 0.08% max for 316 — which is what protects weld-zone corrosion resistance.

Mechanical Properties

Grade	Tensile Strength (min, MPa)	Yield Strength 0.2% Proof (min, MPa)	Elongation (min, %)	Hardness (HRB max)	Hardness (HB max)

Note: values above are indicative allowable pressures per common reference tables for this pipe schedule/size family and should be verified against project-specific engineering data — and against your grade's actual allowable stress values — before use in design calculations. 316L's lower strength versus 316 can mean a slightly reduced allowable pressure at a given wall thickness; check with your engineer.
