OEM Design High Precision Forging Ring Nickel Alloy 718/625/825/925

Nickel alloy 718 (often referred to as Inconel 718), 625 (Inconel 625), 825 (Incoloy 825), and 925 (Incoloy 925) are part of a family of superalloys with high resistance to corrosion and are well-suited for service in extreme environments. Forging rings made from these materials are used in applications requiring high strength and resistance to harsh conditions, such as high temperatures and corrosive media.

Here are some details for each alloy, which might be important when considering them for forging rings:

Nickel Alloy 718 (Inconel 718):

• Offers a combination of high strength, impact resistance, and corrosion resistance.
• Can be used at temperatures up to 700°C.
• Contains niobium, which allows for precipitation hardening in addition to its solid-solution strengthening.
• Applications include jet engines, pump parts, and high-temperature bolts.

Nickel Alloy 625 (Inconel 625):

• Features excellent strength and toughness from cryogenic temperatures up to 980°C.
• Has outstanding fatigue and thermal-fatigue strength.
• Highly resistant to corrosion in a wide range of seawater and chemical environments, including acids and chlorine.
• Common in the aerospace industry and in marine applications like submarine propulsion systems.

Nickel Alloy 825 (Incoloy 825):

• Has good resistance to reducing and oxidizing acids, to stress-corrosion cracking, and to localized attack such as pitting and crevice corrosion.
• Is particularly useful in sulfuric and phosphoric acids environments.
• Typically used in chemical processing, pollution-control equipment, oil and gas piping, and nuclear fuel reprocessing.

Nickel Alloy 925 (Incoloy 925):

• Offers a high level of corrosion resistance comparable with Alloy 825, but with enhanced strength and hardness obtained by adding aluminum and titanium in addition to nickel, chromium, and molybdenum.
• Is particularly effective for applications exposed to sulfide environments and downhole conditions in oil and gas wells.
• Utilized in parts and components for gas compression equipment and marine hardware.

When specifying a forging ring, here's the typical information that might be required:

• Material Specification: Alloy number, any special heat treatment or conditions.
• Dimensions: Outer diameter, inner diameter, thickness, and any critical tolerances.
• Mechanical Properties: Yield strength, tensile strength, elongation, hardness.
• Certifications Required: Such as ASTM, ASME, NACE, API specifications.
• Quantity and Testing Requirements: Any non-destructive testing (like ultrasonic or X-ray), and mechanical testing (tensile, impact).
• Surface Finish: Requirements or standards for machining and finishing.

Each of these superalloys is manufactured to meet specific industry standards and customer requirements, ensuring that they fulfill their intended use with high performance and longevity.
