ASTM B564 N06625 Nickel Alloy Forgings: 225/310mm Diameter Custom Options

ASTM B564 UNS N06625 Nickel Alloy Forgings are high-performance, precision-engineered components manufactured to meet the stringent requirements of ASTM B564 (the global standard for nickel alloy forgings). Crafted from UNS N06625 (Inconel 625), these forgings deliver exceptional corrosion resistance, high-temperature stability, and mechanical strength — making them ideal for the most demanding industrial environments.

Material Overview – UNS N06625 (Alloy 625)

UNS N06625 is a solid-solution strengthened nickel-based alloy known for its outstanding resistance to pitting, crevice corrosion, oxidation, and stress corrosion cracking. The addition of molybdenum and niobium enhances strength without the need for heat treatment, making Alloy 625 ideal for severe service conditions.

Material Properties of UNS N06625

Extreme Temperature Resistance

Maintains mechanical strength up to 1000°C (1832°F) — ideal for high-heat applications like aerospace engines or chemical reactor components.

Superior Corrosion Resistance

Resists pitting, crevice corrosion, and stress corrosion cracking in harsh environments (e.g., seawater, sulfuric acid, chloride-rich solutions).

High Mechanical Strength

Excellent tensile, fatigue, and creep strength, even after long-term exposure to extreme conditions.

Weldability & Fabricability

Can be welded, machined, and formed into complex shapes (critical for custom industrial components).

Superior INCONEL 625 Alloy: INCONEL 625 (UNS N06625) is a solid solution strengthened nickel-based superalloy with molybdenum and niobium as the main strengthening elements. It does not achieve strength through precipitation hardening, but rather relies on the solid solution strengthening of the nickel-chromium matrix by molybdenum and niobium. This gives it stable and excellent mechanical properties over a wide temperature range.

Advantages of Precision Forging: Compared to traditional machining methods, precision forging significantly refines the grain structure of the material, thereby improving the strength, toughness, and fatigue resistance of the product. This means that the forged rings you provide can withstand extremely high mechanical and thermal stresses, resulting in a longer service life in harsh environments. The forging process also eliminates internal defects, improving the density and integrity of the material.

Typical Applications

ASTM B564 UNS N06625 nickel alloy forgings are widely used in industries requiring extreme durability and corrosion resistance, including:

• Oil & gas equipment (valve bodies, stems, flanges)

• Chemical processing components

• Marine and offshore structures

• Power generation and heat-resistant parts

• Aerospace and high-stress mechanical components
