Duplex stainless steels, such as Grade 2205 (UNS S31803/S32205), offer roughly twice the yield strength of standard austenitic grades like 304 and 316. They also boast exceptional resistance to stress corrosion cracking, particularly in chloride environments.
SRG Fasteners supplies Duplex 2205 fasteners for offshore oil rigs, desalination plants, and chemical processing facilities where extreme durability is required.
Frequently Asked Questions
Why use Duplex steel instead of SS 316?
Duplex offers double the yield strength and vastly superior resistance to chloride stress corrosion cracking, making it ideal for harsh marine and chemical environments.
