Pressure vessels
Durable Stainless Steel for Pressure Vessels
Pressure vessels face rigorous wear challenges due to high-stress environments. Our stainless steel solutions offer superior resistance to wear and corrosion.
The service challenge
In pressure vessels, common wear mechanisms include impact and sliding abrasion, often leading to pitting and material loss. Typically, the weakest points are joints and weld areas, where fatigue can exacerbate wear failures.
Recommended product by component
| Component | Grade | Thickness | Why |
|---|---|---|---|
| Pressure Vessel Shells | S31603 | 5-50 | Provides excellent corrosion resistance and durability. |
| Pressure Vessel Ends | S30400 | 5-30 | Offers a good balance of toughness and weldability. |
| Reinforcement Plates | S34700 | 10-40 | Enhances mechanical strength while resistive to intergranular corrosion. |
| Nozzle Rings | S32205/S31803 | 10-25 | Dual-phase structure provides high strength and superior pitting resistance. |
| Internal Baffles | S31008 | 3-20 | Optimized for high-temperature resistance and oxidation durability. |
Selecting the right product
