Alloy 2205 Bolts Pitting Resistance Rating
PREN guides fastener sizing for coastal/offshore buyers; values below are typical, not spec limits
This is why 2205 duplex fasteners are widely specified for coastal plants in South Africa, desalination lines in the UAE, and marine terminals in Kenya and Canada, ahead of standard 316 stainless.
UNS S32205 Threaded Rod Thread Series Guide
We cut whichever thread series matches your existing plant, so replacement fasteners fit first time.
UNF/UNC serve US/Canadian plants, BSW/BSF suit UK-legacy/South African installs, and Metric covers Middle East, European, and Southeast Asian projects
Duplex Screw Fitment & Anti-Galling Guidance
Duplex threads gall more than carbon steel if run dry — torque varies by lubricant, fit, and joint, so we confirm figures per quote
