Monel K-400-UNS N04400-BOLTS-NUTS-STUDS- fasteners

Monel K-400-UNS N04400-BOLTS-NUTS-STUDS- fasteners:

Monel K-400, also known as UNS N04400, is a nickel-copper alloy renowned for its excellent corrosion resistance in various environments, including seawater, acids, and alkaline solutions. Its unique composition provides high strength and toughness, making it suitable for bolts, nuts, studs, and washers in marine, chemical processing, and aerospace industries.

- **Chemical Composition**: 
- Nickel (Ni): 63.0-70.0% 

- Copper (Cu): 28.0-34.0% 
- Iron (Fe): 2.5% max 
- Manganese (Mn): 2.0% max 
- Carbon (C): 0.3% max 
- Silicon (Si): 0.5% max 
- Sulfur (S): 0.024% max

- **Mechanical Properties**: 

- Tensile Strength: ≥70 ksi (482 MPa) 
- Yield Strength (0.2% Offset): ≥28 ksi (193 MPa) 
- Elongation (% in 2 inches): ≥35% 
- Hardness (Brinell): ≤75 HB.

- **Why Use Monel K-400 Studs and Bolts**:

  1. **Corrosion Resistance**: Monel K-400 studs and bolts exhibit exceptional resistance to corrosion in marine environments, including seawater, making them ideal for shipbuilding, offshore oil and gas, and marine applications.

  2. **High Strength and Toughness**: With its high nickel and copper content, Monel K-400 provides excellent strength and toughness, ensuring reliable performance in demanding conditions subjected to high loads and vibrations.
