310 Stainless Steel Sheet – The Ultimate High-Temperature Material for Extreme Heat Environments
When your application demands continuous service above 800 °C, 310 Stainless Steel Sheet is the material that stands the test of time. With a unique combination of 25 % chromium and 20 % nickel, this austenitic grade offers outstanding oxidation resistance up to 1100 °C and continuous operation to 1150 °C—far exceeding the limits of 304, 316, or 321 stainless steels. From furnace linings and radiant tubes to thermocouple shields and petrochemical crackers, 310 Stainless Steel Sheet maintains creep strength, resists thermal fatigue, and minimizes costly downtime in the most extreme thermal environments.

FAQ – 310 Stainless Steel Sheet
-
What is the continuous temperature limit?
1150 °C in air; intermittent up to 1100 °C [^4^]. -
How does 310 differ from 310S?
310S is low-carbon (0.08 % max) for better weldability and thermal cycling. -
Which finish is best for furnace linings?
No.1 HRAP finish is standard; bright annealed 2B can be used when lower emissivity is desired. -
What affects the 310 stainless steel sheet price?
LME nickel, chromium, energy costs, thickness tolerance, and cutting pattern—our live calculator shows every component. -
Can I download a 310 stainless steel material property data sheet?
Yes, PDF is auto-generated after RFQ and includes creep curves from 600 °C to 1000 °C. -
Which mills are the top 310 stainless steel sheet factories in China?
TISCO, Tsingshan, and Baosteel are leading producers; we hold mill-direct allocation agreements with all three. -
Is 310 magnetic?
Austenitic grades are generally non-magnetic after annealing; slight magnetism may appear after heavy cold work. -
How fast can you deliver from your China base?
7 days production + 3–5 days ocean freight to Asian ports; 10 days to EU/US warehouses.
