ASTM B160 UNS N02200 / UNS N02201 Overview
Aurum Overseas is a leading ASTM B160 UNS N02200 Threaded Bars Supplier & Exporter and ASTM B160 UNS N02201 Threaded Bars Supplier & Exporter, stocking commercially pure nickel fasteners for chemical processing. Manufactured to ASTM B160 standards, these studs deliver high electrical conductivity and complete resistance to caustic alkalis across all concentrations.
Our inventory features certified Nickel Alloy 200 Threaded Rods and low-carbon Nickel Alloy 201 Threaded Rods tailored for specific temperature limits. While UNS N02200 is used for service below 315 °C (600 °F), UNS N02201 restricts carbon to 0.02% max to prevent graphite embrittlement above 315 °C (600 °F).
Built for caustic soda evaporators, synthetic fiber equipment, and halogenation reactors, our all-thread rods deliver long-term joint reliability. Contact Aurum Overseas for direct factory quotes, custom cut-to-length studs, and rapid global delivery.

Key Advantages of Nickel Alloy 200/201 Threaded Rods
Caustic Chemical Defense
99.0% minimum pure Nickel prevents corrosion and rusting in all concentrations of sodium hydroxide (caustic soda).
Graphite-Free High Heat (Nickel 201)
Ultra-low carbon content (0.02% max) stops internal cracking and weakening above 315 °C (600 °F).
Dry Halogen Gas Protection
Strong resistance to dry chlorine and fluorine gas damage in severe chemical synthesis units.
High Shock & Vibration Resistance
Outstanding 45% elongation allows studs to absorb mechanical shock and thermal cycles without snapping.
Quality Testing & Inspection
Aurum Overseas subjects every lot of nickel alloy threaded fasteners to strict quality checks before dispatch:
- Material Composition (PMI): Spectro and XRF testing verifying 99.0% minimum Nickel purity and precise Carbon boundaries per UNS N02200 and N02201 standards.
- Mechanical Strength Verification: Tensile, yield, and 45% minimum elongation testing to guarantee ASTM B160 load compliance.
- Precision Thread Inspection: Go/No-Go gage and pitch micrometer checks ensuring smooth class 2A/3A or 6g fit tolerances.
- MTR Certification: Delivered with complete EN 10204 3.1 Material Test Reports certifying melt heat analysis and physical property test results.
