ASTM SB163 UNS N04400 is a nickel-copper alloy seamless pipe renowned for exceptional corrosion resistance in acidic, alkaline, and marine environments. With high strength, thermal stability (up to 538°C), and superior fabricability, it’s ideal for critical applications in chemical processing, oil & gas, and marine engineering. Manufactured to ASTM SB163 standards, these pipes ensure reliability in extreme conditions.
The corrosion resistance of N04400 stems from its precise nickel-copper balance. Key elements include:
| Element | Content (%) | Element | Content (%) |
|---|---|---|---|
| Nickel (Ni) | 63.0 min | Copper (Cu) | 28.0–34.0 |
| Iron (Fe) | 2.0 max | Manganese (Mn) | 2.0 max |
| Carbon (C) | 0.3 max | Sulfur (S) | 0.024 max |
| Silicon (Si) | 0.5 max |
N04400 alloy is globally recognized under these designations:
| Standard | Equivalent Grade | Standard | Equivalent Grade |
|---|---|---|---|
| UNS | N04400 | EN | NiCu30Fe |
| DIN | 2.4360 | JIS | NW4400 |
| BS | NA 13 | ASME | SB163 |
Meets ASTM SB163 requirements for high strength and ductility:
| Property | Value |
|---|---|
| Tensile Strength | 550 MPa (min) |
| Yield Strength (0.2%) | 240 MPa (min) |
| Elongation (%) | 35% (min) |
| Hardness (Rockwell B) | 90 HRB (max) |
Precision-engineered to ASTM SB163 specifications:
| Parameter | Tolerance |
|---|---|
| Outer Diameter | ±0.8% (OD ≤ 50mm) ±0.5% (OD > 50mm) |
| Wall Thickness | +20% / -0% (Schedules 5S-XXS) |
| Length | +3 mm / -0 mm (Cut Length) |
N04400 pipes excel in corrosive and high-stress environments:
