Product Description
ASTM B564 UNS N04400 MONEL 400 Flange Used in Marine Industry
ASTM B564 specifies forged products made of nickel and nickel alloys.
It covers dozens of common, commercially available nickel alloys, such as UNS N04400, UNS N06625, and UNS N08825. UNS N04400 flanges made from these alloys exhibit excellent corrosion resistance due to the properties of nickel-based materials and are widely used in seawater environments.
In actual production, the manufacturing process, chemical composition, and mechanical properties are subject to strict requirements and must be implemented in accordance with ASTM B564 standards.
| Element | Specification Requirements (Weight % Maximum, Unless Noted) |
| Nickel (Ni) | 63.0 min |
| 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 |
| Aluminum (Al) | 0.5 max* |
| Titanium (Ti) | 0.3 max* |
| Cobalt (Co) | 0.5 max* |
| Residuals | 0.5 max* |
| Property | Specification Requirement | Typical Value (Annealed) |
| Tensile Strength, min | 550 MPa (80 ksi) | 550 - 690 MPa (80 - 100 ksi) |
| Yield Strength (0.2% Offset), min | 240 MPa (35 ksi) | 240 - 410 MPa (35 - 60 ksi) |
| Elongation in 50 mm (2 in), min | 35% | 35 - 50 % |
| Hardness | Reported | ~150 HBW (~80 HRB) |
Why Choose ASTM B564 UNS N04400 for Flanges?
| The decision to specify this material over more common options like 316L stainless steel or duplex steels is based on the following comparative advantages: | |
| Consideration | Advantage of N04400 Flanges |
| Seawater Corrosion | Far superior to stainless steels. Highly resistant to pitting, crevice corrosion, and biofouling in stagnant or fast-flowing seawater. |
| Acid Resistance | Excellent in reducing acids (HCl, HF, H₂SO₄ under non-aerated conditions) where stainless steels fail rapidly. |
| Chloride Stress Corrosion Cracking (SCC) | Immune. This is a critical failure mode for 300-series stainless steels in chloride-containing environments above ~60°C. |
| Strength & Toughness | Maintains good mechanical properties from sub-zero temperatures up to about 480°C (900°F). |
| Fabricability | The annealed forgings are ductile and can be readily machined into complex flange geometries (though they work-harden, requiring proper tooling and technique). |
