Stainless Steel 310 Pipe Manufacturer, Supplier & Exporter in India — Nishra Overseas
Nishra Overseas is a leading Stainless Steel 310 Pipe manufacturer in India, and a dependable 310 Pipe supplier and exporter in India, serving high-temperature process, furnace, and heavy-industrial buyers across domestic and international markets. Whether you're sourcing Stainless Steel 310 Pipe in India for a single project or for ongoing supply, our stock depth and manufacturing capability are built to support both.
310 is an austenitic grade built around a much higher chromium and nickel content than the 300-series grades most buyers start with — typically 24–26% chromium and 19–22% nickel, well above what 304 or 316 carry. That composition is what gives 310 its defining trait: outstanding resistance to oxidation and scaling at sustained high temperatures, holding up in cyclic heat environments up to around 1100°C. Stainless Steel 310 pipe carries a minimum tensile strength of 515 MPa and a minimum yield strength of 205 MPa, with elongation up to 40% and a density of roughly 7750 kg/m³ — noticeably lower than 304 or 316 because of the different alloy balance.
310 also welds easily and offers solid thermal conductivity across the 100–500°C range, which is why it turns up so often in furnace parts, burners, tube hangers, and other equipment that spends its working life at high, cyclic temperatures rather than in corrosive wet environments. It costs more than general-purpose grades because of the higher alloy content, but for genuinely high-temperature service it's usually the more economical long-term choice once you account for service life. As a trusted Stainless Steel 310 Pipe manufacturer, supplier, and exporter in India, Nishra Overseas' goal is straightforward: deliver certified, high-quality 310 pipe and tube at fair, competitive pricing, backed by dependable stock availability.

310's high chromium and nickel content — well above 304 or 316 — is what gives it its scaling and oxidation resistance at sustained high temperatures, rather than corrosion resistance in wet chloride environments, which is more the domain of molybdenum-bearing grades like 316.

Figures are per 100 mm cut length for seamless tube; confirm exact weights against mill data before quoting large orders. 310's higher density than carbon steel and slightly lower density than 316 will shift these figures marginally — verify against your grade's exact density before final costing.
