Inconel 604 Nickel Alloy ，1

### **Product Introduction: Nickel-Chromium-Iron Alloy (A Generic 60Ni-15Cr Grade)** It is important to preface that **"Inconel 604" is not a standard, commercially recognized designation under the INCONEL® trademark** held by Special Metals Corporation. Extensive searches through major standards organizations (ASTM, ASME, UNS, DIN) and alloy producer databases do not list an "Alloy 604" or "INCONEL 604." Based on the nomenclature, it is highly probable that the intended reference is to a **generic nickel-chromium-iron alloy with a composition of approximately 60% Ni, 15% Cr, and balance Fe**. This family of alloys shares characteristics with well-known grades like Alloy 600 but is a distinct, often less common or proprietary formulation, potentially optimized for specific electrical or high-temperature applications. The following introduction is based on the typical properties of a **60Ni-15Cr-Fe alloy**. --- ### **Hypothetical Profile: 60Ni-15Cr-Fe Alloy** This nickel-chromium-iron alloy offers a good balance of oxidation resistance, high-temperature strength, and favorable electrical properties. It is typically used in applications requiring reliable performance in moderately high-temperature and corrosive environments, such as industrial heating elements and electronic components. --- ### **International Standards & Material Equivalents** Since this is not a standard UNS alloy, equivalent specifications are not standardized. It may be covered under proprietary or industry-specific specifications. | Standard Type | Potential Designation | Note | | :--- | :--- | :--- | | **UNS (USA)** | Not Assigned | No UNS number exists for "Inconel 604". | | **Proprietary** | Manufacturer's Specific Code | Varies by producer. | | **Historical/Military** | Possibly older MIL specifications | For specific component procurement. | > **Note:** For a verified and widely available alternative with a similar Ni-Cr-Fe system, please consider **INCONEL® Alloy 600 (UNS N06600)** or **INCONEL® Alloy 601 (UNS N06601)**. --- ### **Typical Chemical Composition (for a 60Ni-15Cr-Fe type alloy)** | Element | Content (%) (Estimated) | | :--- | :--- | | **Nickel (Ni)** | ~60 | | **Chromium (Cr)** | ~15 | | **Iron (Fe)** | Balance | | **Manganese (Mn)** | < 1.5 | | **Silicon (Si)** | 0.5 - 1.0 | | **Carbon (C)** | < 0.10 | | **Aluminum (Al)** | < 0.5 | | **Copper (Cu)** | < 0.5 | --- ### **Representative Physical Properties** | Property | Value (Estimated) | | :--- | :--- | | **Density** | ~8.3 g/cm³ | | **Melting Point** | ~1370 - 1425 °C (~2500 - 2600 °F) | | **Thermal Conductivity** | ~12 W/m·K (at 20°C) | | **Electrical Resistivity** | ~1.05 μΩ·m (at 20°C) | | **Modulus of Elasticity** | ~200 GPa (29 x 10⁶ psi) | | **Coefficient of Thermal Expansion** | ~14.0 μm/m·°C (20-100°C) | | **Magnetic Response** | Typically non-magnetic | --- ### **Representative Mechanical Properties (Annealed Condition)** | Property | Value (Estimated) | | :--- | :--- | | **Tensile Strength** | 620 - 750 MPa (90 - 110 ksi) | | **Yield Strength (0.2% Offset)** | 250 - 350 MPa (36 - 51 ksi) | | **Elongation** | 35% - 45% | | **Hardness (Rockwell B)** | 75 - 85 HRB | --- ### **Key Characteristics & Advantages** 1. **Good Oxidation Resistance:** The chromium content provides a protective oxide scale, offering resistance to air oxidation at elevated temperatures. 2. **High-Temperature Strength:** Maintains useful mechanical strength and creep resistance at high temperatures. 3. **Favorable Electrical Properties:** The composition lends itself to use as a resistance heating material. 4. **Good Fabricability:** Can be machined, formed, and welded with standard techniques for nickel-chromium alloys. --- ### **Potential Product Applications** * **Industrial Heating:** Components for electric resistance furnaces, heating element wire and strip. * **Electronics:** Lead wires, terminals, and other components requiring a combination of corrosion resistance and specific electrical properties. * **Thermal Processing:** Furnace fixtures, trays, and other components exposed to moderately high temperatures. ### **Summary and Important Clarification** The alloy referred to as **"Inconel 604" is not a standard, commercially available grade** under the INCONEL trademark. The information provided above is a hypothetical profile for a generic **60Ni-15Cr-Fe alloy**, which shares a family resemblance to established grades but lacks the specific, verified property data and international standards of alloys like INCONEL 600 or 601. **For critical applications, it is strongly recommended to select a well-documented and standardized alloy** with guaranteed properties and available mill certifications. Please consult with a reputable alloy supplier to identify the most suitable material for your specific requirements.
