Product Description
Product Overview

This High Temperature Resistant 310S Seamless Stainless Steel Boiler Tube is engineered for continuous service in the hottest zones of power plant boilers, where ordinary carbon steel and lower alloy grades would scale and fail. The 310S austenitic grade carries 25 percent chromium and 20 percent nickel, giving it a very stable austenitic structure that resists oxidation, scaling and carburisation at elevated temperatures. Because the tube is formed by the seamless process, there is no weld seam to become a weak point under thermal cycling, making it a preferred material for superheater, reheater and high temperature steam lines.

The tube is supplied in outside diameters from 6 mm to 630 mm and wall thickness from 0.5 mm to 30 mm, with bright annealed or pickled and annealed surface finishes. Each batch is eddy current tested, hydro tested and supplied with a mill test certificate, so engineering teams can verify heat number, chemistry and mechanical properties against their specifications before the tube enters the boiler.

Key Advantages
  • 25 percent chromium and 20 percent nickel content provides outstanding high temperature oxidation resistance.
  • Seamless body resists thermal fatigue and creep better than welded tubing in boiler service.
  • Stable austenitic structure maintains strength and ductility across repeated heating and cooling cycles.
  • Eddy current and hydro tests on every batch ensure reliable pressure tightness.
  • Full material traceability with heat number and mill test certificate.
  • Custom lengths and end preparations reduce on-site fabrication and downtime.
Typical Applications
  • Power plant superheater and reheater tubes
  • Industrial boiler high temperature sections
  • Heat treatment furnace and radiant tubes
  • Petrochemical cracker and reformer piping
  • High temperature steam and process lines
Frequently Asked Questions
Q: Why choose 310S over 304 or 316 for boiler tubes?

A: The higher chromium and nickel content of 310S gives it far greater resistance to oxidation and scaling above 900 °C, where 304 and 316 would quickly lose strength and form heavy scale.

Q: Which standard does this boiler tube follow?

A: It is manufactured to ASTM A213 and ASME SA213, the specifications most widely required for seamless ferritic and austenitic alloy steel boiler, superheater and heat exchanger tubes.

Q: Can the tube be supplied in custom sizes?

A: Yes. We produce outside diameters from 6 mm to 630 mm and wall thickness from 0.5 mm to 30 mm, and cut to your specified length and end finish.

Q: Do you offer third party inspection?

A: We can arrange inspection by SGS, BV or TUV and provide EN 10204 3.1 or 3.2 certificates. Please contact us with your technical specification for a quotation.
