Zeron Fastners
ZERON 100 Mechanical Properties
General Strength Profile
The ZERON 100 Super Duplex alloy (UNS S32760) is known for offering mechanical properties significantly higher than traditional Duplex (UNS S31803) and standard austenitic stainless steels (like 316). It achieves roughly twice the yield strength of 316L, allowing for lighter component design without compromising safety or load-bearing capacity. These properties are maintained across a wide operating temperature range.
Typical Mechanical Properties (Solution Annealed Condition)
| Property | Metric Value | US Value |
|---|---|---|
| Tensile Strength (min) | 750 MPa | 109 ksi |
| Yield Strength (0.2% Offset min) | 550 MPa | 80 ksi |
| Elongation (min) | 25% | 25% |
| Hardness (max) | 275 HB | 275 HB |
Performance Grade Comparison
For fastener applications, ZERON 100 is often supplied in specific conditions (FG or SA) that further tailor its mechanical output. The Fastener Grade (FG) uses strain hardening to achieve properties comparable to ASTM A193 Grade B7, ensuring suitability for critical flange bolting in high-pressure and elevated temperature environments.
