Description
Duplex 2205 M24 plain washers are high-strength, corrosion-resistant fasteners made from nitrogen-enhanced duplex stainless steel (UNS S32205 / S31803).
Manufactured from UNS S32205/S31803 Duplex Stainless Steel, these fasteners deliver nearly twice the yield strength of conventional austenitic stainless steels, along with excellent resistance to chloride-induced stress corrosion cracking. Ideal for demanding marine, chemical, petrochemical, and offshore applications.
Key Features – Duplex 2205 Fasteners
- High Strength: Nearly twice the yield strength of standard austenitic stainless steels.
- Excellent Corrosion Resistance: Superior resistance to pitting, crevice corrosion, and chloride environments.
