Common Types of Flanges
- Flange de Pescoço de Solda:
Ideal for severe,high-pressure environments;features a tapered hub welded directly to the pipe. - Flange deslizante:
Slipped over the pipe and welded inside and out;preferred for lower-pressure setups due to easier alignment. - Flange Cego:
Used to securely block or seal off a piping system or pressure vessel opening. - Flange de junta sobreposta:
Paired with a stub end;helpful for systems requiring frequent cleaning or rapid dismantling. - Flange Faces:
Available in Flat Face (FF),Raised Face (RF),and Ring Type Joint (RTJ) for heavy-duty metal-to-metal sealing.

Chemical Composition of Monel 400 Flanges, wt.%
| Elemento | Ni + Co | Cu | Fe | Mn | Si | C | S |
|---|---|---|---|---|---|---|---|
| Inconel 600 | ≥ 63.0% | 28.0 - 34.0 | ≤ 2.50 | ≤ 2.00 | ≤ 0.50 | ≤ 0,30 | ≤ 0.024 |
Crucial Composition Nuances
- The Nickel-Copper Balance:
The high nickel content provides exceptional resistance to stress corrosion cracking and alkaline environments,while the copper offers superior protection against marine environments and hydrofluoric acid. - Wrought vs. Cast Flanges:
The limits above apply strictly to standard wrought/forged flanges (UNS N04400 / ASTM B564).If your flanges are manufactured via a casting process instead of forging,they fall under ASTM A494 (Grade M35-1 or M35-2),which allows a higher Silicon content to improve molten metal fluidity during pouring.
Room-Temperature Mechanical Properties of Monel 400 Flanges
| Propriedade mecânica | Resistência à tracção | Força de rendimento | Alongamento | Dureza |
|---|---|---|---|---|
| Monel 400 | ≥ 483 MPa(70 ksi) | ≥ 172 MPa(25 ksi) | ≥ 35% | 135 – 179 HBW |
Crucial Engineering Characteristics
- No Heat-Treatment Hardening:
Monel 400 is a solid-solution alloy.It cannot be hardened or strengthened via thermal heat treatment.Increased strength is only achievable through cold working. - Excellent Cryogenic Performance:
Unlike carbon steels,Monel 400 does not undergo a ductile-to-brittle transition.At sub-zero and cryogenic temperatures,its tensile and yield strengths increase significantly while its ductility and toughness remain virtually unaffected. - High-Temperature Limits:
While the material retains good mechanical stability at elevated temperatures,pressure vessel codes (like ASME Section VIII) restrict its maximum pressure-rating design use to 900°F (482°C).Above this temperature,the material is subject to creep.

Our Core Capabilities in Manufacturing Monel 400 Flanges
Advanced Precision Forging & Material Integrity
- Grain Flow Optimization:
Our forging process refines the internal grain structure of the nickel-copper alloy,maximizing mechanical toughness and fatigue resistance. - Flaw Detection:
Every forged blank undergoes comprehensive NDT,including UT and liquid penetrant testing,to guarantee zero internal voids or surface cracks before machining.
High-Tolerance CNC Machining
- Precisão dimensional:
Utilizing multi-axis CNC turning centers,we achieve tight-tolerance finishes on critical sealing surfaces,including RF and RTJ grooves. - Surface Finish Control:
We maintain strict control over surface roughness to ensure optimal gasket seating,preventing micro-leakages in high-pressure or hazardous chemical lines.
Metallurgical Testing & Traceability
- PMI:
Every single flange is verified via handheld XRF/OES spectrometers to confirm the exact 63% Ni / 28–34% Cu chemical footprint. - Mechanical Validation:
We conduct destructive room-temperature and cryogenic tensile,yield,and impact testing on representative sample lots. - 100% Traceability:
All shipments are accompanied by EN 10204 3.1 MTCs,tracking the material from the raw ingot heat number to the final machined product.
Custom Engineering & Flexible Production
- Broad Dimensional Range:
We manufacture flanges from 1/2″ to 72″ across all pressure classes (150# to 2500#).
Rate: 150 LBS, 300 LBS, 600 LBS, 900 LBS, 1500 LBS, 2500 LBS - Bespoke Designs:
Our engineering team can manufacture custom dimensions,heavy-barrel configurations,anchor flanges,or tailored long-weld necks based directly on your project’s proprietary blueprints.
FAQs About Monel 400 Flanges
Yes,Monel 400 exhibits excellent weldability.When joining it to dissimilar metals like carbon steel or stainless steel,specialized welding consumables like ERNiCu-7 (Monel Filler Metal 60) or ENiCu-7 (Monel Welding Electrode 190) are used.However,engineers must evaluate the operating environment,as welding Monel to steel can trigger galvanic corrosion if exposed to an electrolyte like seawater.
While stainless steel 316 performs well in mild environments,it suffers from severe pitting,crevice corrosion,and chloride-induced SCC in stagnant or warm seawater.Monel 400 is virtually immune to chloride stress cracking and provides exceptional resistance to fast-flowing brackish water and biofouling,resulting in a much longer operational lifespan.
Monel 400 should be strictly avoided in highly oxidizing chemical environments.Because of its high copper content,it undergoes rapid,catastrophic corrosion when exposed to nitric acid,nitrous gases,and ammonia-rich systems.It will also corrode quickly in highly aerated hydrochloric or sulfuric acid solutions.
The high cost is driven by its raw materials—principally nickel (minimum 63%) and copper.Nickel is a premium,volatilely priced commodity.Additionally,Monel 400 work-hardens rapidly during manufacturing,which accelerates tool wear and demands slower CNC machining speeds,increasing overall production costs.
