Stainless Steel 304 Fasteners
Most Trusted AISI 304L Nut Bolts Supplier in India
Are these 304 SS fasteners suitable for high-temperature?
SS 304 fasteners can handle intermittent high temperatures but prolonged use above 800°C can lead to sensitization, which effects its corrosion resistance properties. For high temperature applications you can opt for stainless steel 304h fasteners which is highly recommended.
| Temperature Range | Behavior |
|---|---|
| Up to ~870°C (1600°F) | Maintains good oxidation resistance |
| 925°C (1700°F) | Not suitable for long-term exposure |
| Over 1000°C | Loses mechanical properties and structural integrity |
