ASTM A213 Tube Manufacturer, Supplier & Exporter in India
Nishra Overseas is a Mumbai-based manufacturer, supplier and exporter of ASTM A213 / ASME SA213 seamless ferritic and austenitic alloy-steel tubes, built for boiler, superheater, condenser and heat-exchanger service where reliability at high temperature and pressure is non-negotiable.
We supply ASTM A213 tube to fabricators, EPC contractors, boiler OEMs, and process plants across India, and export to customers throughout the Middle East, Southeast Asia, Africa and Europe. Our stock covers the most-used austenitic and ferritic alloy grades in standard sizes, and we also produce tubes to custom lengths, U-bends and non-standard dimensions against client drawings.
Every consignment is backed by complete documentation — Mill Test Certificates as per EN 10204 3.1, chemical composition and mechanical property reports, hydrostatic and NDT reports where applicable, and third-party inspection on request — so buyers can verify quality before the material even leaves our facility.

ASTM A213 Grades We Supply
ASTM A213 TP304 / TP304L / TP304H Tube
General-purpose austenitic stainless tube suited to moderate-temperature heat exchanger and process tubing duty, with TP304L offering lower carbon for better weldability.
ASTM A213 TP316 / TP316L / TP316H / TP316Ti Tube
Molybdenum-alloyed grades that hold up better against chlorides and aggressive process fluids than the 304 series, commonly specified for chemical and marine-adjacent environments.
ASTM A213 TP321 / TP321H Tube
Titanium-stabilized grade that resists sensitization and intergranular corrosion at elevated temperatures, often used where welded joints will see sustained heat.
ASTM A213 TP347 / TP347H Tube
Niobium-stabilized grade with strong high-temperature creep resistance, widely specified for superheater tubing in power boilers.
ASTM A213 TP310S Tube
High chromium-nickel austenitic grade offering strong oxidation resistance for the hottest zones of a boiler or furnace circuit.
ASTM A213 Ferritic Alloy Steel Tube (T5, T9, T11, T12, T22, T91)
Chromium-molybdenum alloy tubes built for high-pressure, high-temperature boiler and superheater service, offering a cost-effective alternative to austenitic grades where the application allows.
