**Duplex Steel: Strength and Corrosion Resistance That Exceeds 316**
When it comes to fasteners, 316 stainless steel has long been a popular choice due to its versatility and corrosion resistance. However, if you're searching for a step-up in performance without stretching your budget too thin, Duplex alloys could be the perfect solution. These fasteners boast twice the strength of 316 stainless steel while offering superior corrosion resistance, making them ideal for demanding environments.
This newsletter delves into the differences between Duplex 2205 (S32205) and Super Duplex 2507 (S32750) fasteners, highlighting scenarios where upgrading from 316 stainless steel makes sense.

**Why Opt for Duplex Alloys Over 316 Stainless?**
Duplex steel fasteners should be your go-to choice when the limitations of 316 fasteners become apparent—whether it's from a mechanical standpoint or in terms of corrosion resistance. Both Duplex 2205 and Super Duplex 2507 alloys outperform 316 stainless steel by offering approximately double the yield strength. Moreover, they excel in corrosion resistance, with Super Duplex 2507 taking the lead as the more robust option.

**Taking It Further: The Zeron 100 Option**
Before transitioning to costly nickel alloys, consider Zeron 100 fasteners (also referred to as F55 or UNS S32760). This variant of Super Duplex 2507 provides even greater corrosion resistance, making it an excellent middle ground between cost and performance.
