1. Introduction to Monel 400 WNRF Flanges
Monel 400 (UNS N04400) weld neck raised face (WNRF) flanges, manufactured under ASTM B564 standard, deliver
exceptional resistance to corrosive environments. As a nickel-copper alloy, Monel 400 maintains superior mechanical
properties from cryogenic temperatures up to 1000°F (540°C), making it ideal for critical applications in marine, chemical,
and oil & gas industries. These flanges ensure leak-proof performance under high-pressure conditions.
| Element | Composition (%) | ASTM B564 Requirement |
|---|---|---|
| Nickel (Ni) | 63.0 min | 63.0 min |
| Copper (Cu) | 28.0–34.0 | 28.0–34.0 |
| Iron (Fe) | 2.5 max | 2.5 max |
| Manganese (Mn) | 2.0 max | 2.0 max |
| Carbon (C) | 0.3 max | 0.3 max |
| Silicon (Si) | 0.5 max | 0.5 max |
| Sulfur (S) | 0.024 max | 0.025 max |
Monel 400 is globally recognized under multiple standards:
| Standard | Equivalent Designation |
|---|---|
| UNS | N04400 |
| EN | NiCu30Fe (2.4360) |
| ASME | SB-564, SB-127 |
| ASTM | B564, B127 |
| NACE MR0175 | Compliant |
Flanges meet ASTM B564 minimum requirements for forged products:
| Property | Value | Test Method |
|---|---|---|
| Tensile Strength | 80 ksi min (550 MPa min) | ASTM E8/E8M |
| Yield Strength (0.2% Offset) | 35 ksi min (240 MPa min) | ASTM E8/E8M |
| Elongation | 30% min | ASTM E8/E8M |
| Hardness | 65–95 HRB | ASTM E18 |
| Impact Strength (Charpy) | 70 ft-lb min (95 J min) | ASTM E23 |
