321H Stainless Steel Sheet, SS 321H Sheets Stockist
GNEE is a globally recognized supplier of high-quality ASTM A240 Gr. 321/321H stainless steel sheets in various sizes, thicknesses, and specifications, with a range of surface treatments such as 2B, BA, patterned, and brushed.
ASTM A240 SS321H (UNS S32109) is a high-carbon austenitic stainless steel stabilized by the addition of titanium (Ti). As a high-carbon version of 321 stainless steel, 321H is designed to enhance creep strength and fracture resistance at high temperatures, providing superior strength and creep resistance, making it particularly suitable for components requiring high-temperature strength.
Our cold-rolling process ensures that 321H steel sheets possess extremely high dimensional accuracy, a smooth surface quality, and excellent mechanical properties. This material exhibits exceptional resistance to intergranular corrosion in a temperature range of 800°F (427°C) to 1500°F (816°C), making it the preferred choice for extreme industrial environments.
321H Stianless Steel Plate Applications
Aerospace: Piston engine exhaust manifolds, gas turbine components.
Chemical Processing: High-temperature organic acid containers, pressure vessels.
Oil Refining Industry: Hydrocracking units, heat exchangers.
Coal Power Generation: Superheater tubes, reheater components.

What is the hardness of 321H plate?
The hardness of 321H stainless steel plate (UNS S32109) is generally rated at a maximum of 217 Brinell (HB) or approximately 95 Rockwell B (HRB) in the annealed condition.
Are SS 321H sheets suitable for welding?
Yes, SS 321H sheets are highly suitable for welding and are specifically designed for applications requiring excellent weldability and high-temperature service. As a titanium-stabilized austenitic stainless steel, 321H is engineered to prevent intergranular corrosion in the heat-affected zone (HAZ) during welding.
Quality Inspection
ASTM A240 321H cold-rolled steel sheet material certificates we provide are all tested in a CNAS-accredited laboratory, ensuring that the data deviation is better than the national standard by more than 15%. Through rigorous intergranular corrosion and grain size rating, we provide core data support and full life-cycle traceability for high-pressure/high-temperature applications such as pressure vessels and high-temperature compensators.
