Mô tả sản phẩm
321 321H Titanium Stabilized Stainless Steel Sheet Plate 0.5mm-60mm Thickness for High Temperature Heat Exchanger
321 / 321H Titanium Stabilized Stainless Steel Sheet Plate
The 321 and 321H stainless steel sheets are titanium-stabilized austenitic chromium-nickel alloys engineered for exceptional performance in high-temperature environments. The deliberate addition of titanium (minimum 5 * C content) effectively prevents chromium carbide precipitation at grain boundaries, ensuring immunity to intergranular corrosion even after extended exposure to the critical 425-900°C sensitization range. Grade 321H, with controlled higher carbon content (0.04-0.10%), provides superior elevated temperature strength for structural applications.
Key Features
- Titanium Stabilization: Ti content ≥ 5 * Carbon eliminates sensitization and intergranular attack after welding or thermal cycling
- High Temperature Resistance: Excellent scaling resistance up to 900°C in continuous service, 816°C in intermittent service
- Superior Creep Strength (321H): Controlled higher carbon provides enhanced creep rupture strength at elevated temperatures
- Excellent Weldability: No post-weld annealing required thanks to titanium stabilization
- Good General Corrosion Resistance: Comparable to 304/304L in most environments with added high-temperature capability
- Thermal Fatigue Resistance: Outstanding performance under cyclic heating and cooling conditions
