Zeron Fastners
ZERON 100 FLT (Fasteners for Low Temperature) Specification
Product Overview: Enhanced Cryogenic Efficiency
ZERON 100 FLT (Fasteners for Low Temperature) is a specialized variant of ZERON 100 Super Duplex designed for environments where both severe corrosion and low-temperature performance are critical. This grade offers enhanced efficiency and mechanical integrity when compared to the ZERON 100 FG grade at cryogenic temperatures.
FLT is essential in applications such as liquefied gas processing, storage, and transport, where the risk of embrittlement from extreme cold must be mitigated without compromising corrosion resistance.
Low Temperature Equivalence and Impact Testing
ZERON 100 FLT is specifically engineered to meet or exceed the impact requirements of alloy grades typically used for low-temperature bolting.
| Characteristic | ZERON 100 FLT Grade | Reference Standard (Low Temp.) |
|---|---|---|
| Corrosion Grade | High (Super Duplex) | N/A |
| Low-Temperature Performance | More efficient than ZERON 100 FG | N/A |
| Mechanical Equivalence | High Strength (Impact Tested) | ASTM A320 Grade L7 |
Corrosion Resistance and Applications
While referencing ASTM A320 Grade L7 for mechanical properties, ZERON 100 FLT retains the superior Super Duplex corrosion resistance inherent to ZERON 100 (UNS S32760). This makes it a rare and high-integrity choice for cold applications involving corrosive media, such as cryogenic heat exchangers and processing plants handling highly corrosive liquefied gases or brines.
