Choosing Materials for Corrosion Resistance: Duplex & Nickel Alloys
Material selection basics for harsh environments and critical applications.
SN Bolting is a service-driven specialist in the manufacture and distribution of fully certified, tested and traceable special fasteners and machined components. We support critical industries worldwide — including Oil & Gas, Subsea/Offshore, Power Generation/Energy and Nuclear — with technical accuracy, responsive communication, and documentation you can trust.
Detailed certification packs • On-time delivery updates • Quality focused manufacturing
When quality, traceability, and delivery timelines matter, we deliver more than parts — we deliver confidence through technical expertise and service.
We supply bespoke manufactured components across multiple sectors — with full material traceability, detailed documentation and fast turnaround support.
Upstream, midstream and downstream applications — exploration/production, processing/storage and refinery/plant operations.
Turbines, motors and generators, wind farms, solar equipment and natural gas systems.
Auto claves, condensers, cooling towers, generators, pipelines, pumps, valves, reactors, turbines and waste containment units.
Naval marine & defence, chemical processing, water treatment, renewable energy, petrochemical, heavy engineering, mining and distribution.
We manufacture parts to international standards (ISO/DIN/BS/ASME/ASTM/Werkstoff) and to customer technical drawings. Where drawings aren’t available, we can reverse engineer from sample — including material identification and technical drawing approval prior to manufacture.
Hot forged or machined
