The NA16 Nut, engineered by a leading China-based manufacturer, is a high-performance fastener forged from Incoloy 825—a nickel-iron-chromium alloy renowned for its exceptional resistance to stress corrosion cracking. Available in BSW, DIN, ASTM, and NF standards, this 5/8‑inch nut maintains a hardness below 200 HB and delivers reliable service at continuous operating temperatures up to 550°C. Its balanced combination of mechanical strength and corrosion resistance makes it a preferred choice in chemical processing, oil and gas, power generation, and other high‑temperature industrial sectors. Whether exposed to aggressive media or prolonged thermal cycling, the NA16 Nut ensures secure, leak‑free joints that enhance overall system safety and efficiency.
Why Incoloy 825 Excels at Elevated Temperatures
The alloy’s high‑temperature capability stems from its carefully tuned chemistry:
- Nickel – sustains strength and ductility, preventing embrittlement.
- Chromium – forms a self‑healing Cr₂O₃ scale that resists oxidation.
- Molybdenum – boosts creep resistance and hot strength.
- Titanium – stabilizes the structure against intergranular attack and phase degradation.

High‑Temperature Mechanical Data
| Property | Room Temp. | 500°C | 700°C |
| Tensile Strength (MPa) | ≥586 | ≥520 | ≥450 |
| Yield Strength (MPa) | ≥241 | ≥220 | ≥200 |
| Elongation (%) | ≥30 | ≥25 | ≥20 |
Creep Performance – At 600°C / 100 MPa: creep <0.1% after 1,000 h. At 700°C / 50 MPa: <0.2% after 1,000 h.
Oxidation Resistance – In air at 800°C, weight gain <0.1 mg/cm² (1,000 h); at 900°C, <0.3 mg/cm². The Cr₂O₃ film remains adherent and crack‑free below 900°C, with an oxidation penetration rate <0.01 mm/year.
Summary – With tensile and yield strengths, elongation, and creep resistance that outperform many conventional superalloys, the NA16 Nut from this China-based manufacturer offers a robust, cost‑effective solution for extreme environments. Its proven stability under thermal and corrosive stress ensures long‑term equipment reliability, reducing unplanned downtime and maintenance costs.
