Monel 400 Forged Discs Ni-Cu Corrosion Resistance And Strength Alloy

Monel 400 Forged Discs Ni-Cu Corrosion Resistance And Strength Alloy

ⅠMaterial Nature: The “Genetic Code” of Ni-Cu Alloy

ⅡManufacturing logic: The "performance leap" given by forging

1. The core of the hot forging process
①Temperature window: 900~1100°C (austenitic single-phase area, best plasticity), by upsetting/ring rolling, crushing the coarse grains in the casting state.
②Forge Value:
▶Eliminate casting defects such as looseness and porosity, resulting in density up to 99.9%+;
▶The grains are arranged "streamlined" along the stress direction, and the fatigue resistance is increased by 40~60% (compared to castings).
2. Post-processing and precision
①Machining: Milling flattened end face, finishing outer circle, ensuring dimensional tolerance ±0.1mm, surface roughness Ra≤1.6μm (meeting the requirements of sealing surface assembly).
②Optional solution treatment: 1000~1050°C insulation and then fast cooling to strengthen corrosion resistance (avoid precipitation of carbide at grain boundaries).

ⅢPerformance advantages: The "survival code" for extreme environments

1. Corrosion resistance – "corrosion insulator"

2. Mechanical properties - "strong and tough"
▶Static strength: Tensile strength ≥ 550MPa, yield strength ≥ 240MPa (after forging, cold working can be further increased to 700MPa+).
▶Dynamic performance: High fatigue limit (300MPa@10⁷ cycle), impact toughness (AKV≥100J), suitable for alternating load scenarios.
3. Physical characteristics
Density 8.8g/cm³ (10% heavier than carbon steel, more "pressing" in the same volume), non-magnetic (can be screened by magnet, different from most stainless steels), thermal conductivity 21.6W/(m・K) (better than Inconel alloy, more efficient heat dissipation).

ⅣApplication value: The "key puzzle" of high-end industry
1. Industry adaptation

2. Alternative logic
▶Compared with 316L stainless steel: Corrosion resistance is increased by 5~10 times, especially in hydrochloric acid and seawater environments;
▶Compared with pure nickel (Ni200): 30% lower cost (due to Cu content) while maintaining high corrosion resistance;
▶Compared with castings: 40%+ mechanical properties, suitable for high pressure and dynamic load conditions.

ⅤQuality endorsement: Standards and testing
①Executive standards: ASTM B165 (forging specification), ASME SB165 (nuclear power grade certification).
②Mandatory inspection items:
▶Spectral analysis (accurate determination of Ni and Cu content);
▶Ultrasonic flaw detection (UT, internal defect detection, grade ≥NB/T 47013);
▶Hardness test (HB160~200, annealed state; HB in cold processing up to 250+);
▶Grain size testing (clear forging streamline, grain size ≥ASTM Grade 5).

Summary: Monel 400 forging cake is an industrial core part with dual attributes of "corrosion resistance + strength", unlocking the performance potential through forging, accurately matching the extreme environment such as marine and chemical, from composition to application, every detail serves the ultimate mission of "anti-corrosion and long life".
