Grade 321/321H Stainless Steel Plate
Stainless Metal Grades to Fit Your Needs
Grade 321 stainless steel plate is a standard 18/8 chromium-nickel alloy reinforced by titanium and niobium. The addition of titanium stabilizes this alloy and removes its susceptibility to intergranular corrosion while mitigating carbide precipitation during welding. At elevated temperatures, it resists oxidation and has higher creep and rupture properties than 304/304L stainless steel.
Grade 321H stainless steel plate contains more carbon (between 0.04% to 0.1%) than regular 321 (≥ 0.08%), which enhances its high-temperature performance, including increasing its resistance to cracking or warping due to shifts in temperature.

Choosing 321/321H Plate from Sabre
Both stainless steel grades are the ideal option in high-temperature applications up to 1,650°F.
key advantages and benefits include
- Superior resistance to intergranular corrosion
- Higher strength, creep, and stress rupture properties
- Excellent performance in extremely high-temperature conditions
- Resistant to scaling and phase stability
- Resistant to subsequent aqueous corrosion
- Good resistance to cracking and warping
- Outstanding welding and forming characteristics
- Enhanced durability and toughness
While Grade 321 stainless steel offers numerous benefits and possesses numerous advantageous material properties, it does not transfer well across a high-temperature arc due to its titanium content. Thus, neither grade is recommended as a welding consumable. Also, this stainless steel grade does not polish well, so it should not be used for cosmetic architecture.
