Product Description
NO.1 Surface 321 Hot Rolled Stainless Steel Sheet Thickness 8mm 10mm Annealed Stainless Steel Sheet
Our NO.1 Surface 321 Hot Rolled Stainless Steel Sheet is manufactured from premium titanium-stabilized 321 stainless steel in accordance with ASTM A240, EN 10088-2, and JIS G4304 standards. Featuring a No.1 hot rolled, annealed, and pickled surface finish, this stainless steel sheet provides exceptional high-temperature oxidation resistance, excellent corrosion resistance, and superior mechanical stability.
Available in 8mm and 10mm thicknesses, it is specifically designed for heavy-duty industrial applications where high strength, thermal stability, and long service life are essential. Compared with conventional 304 stainless steel, Grade 321 offers significantly improved resistance to intergranular corrosion and maintains excellent mechanical properties during continuous exposure to elevated temperatures.

Product Features
Excellent High-Temperature Resistance
The addition of titanium effectively stabilizes the microstructure of Grade 321 stainless steel, preventing chromium carbide precipitation during prolonged exposure to temperatures between 450°C and 850°C.
- Continuous service temperature up to 800°C
- Excellent oxidation resistance
- Outstanding thermal stability
- Superior creep resistance
- Reduced risk of sensitization after welding
This makes 321 stainless steel the preferred material for high-temperature industrial equipment.
Superior Corrosion Resistance
NO.1 Surface 321 Hot Rolled Stainless Steel Sheet provides excellent resistance to a wide range of corrosive environments.
It offers outstanding protection against:
- Atmospheric corrosion
- Organic acids
- Oxidizing chemicals
- Industrial pollutants
- High-temperature oxidation
- Intergranular corrosion
The titanium stabilization ensures reliable performance even after welding or prolonged heat exposure.
