Custom UNS R30016 Cobalt Alloy Forging Ring for Machining and Finishing

Haynes Stellite 6B is a cobalt-based superalloy renowned for its exceptional wear resistance, high-temperature strength, and corrosion resistance. It belongs to the Stellite family of alloys, which are widely used in extreme environments such as aerospace, industrial gas turbines, valve components, and chemical processing equipment.

Composition:

• Primary Element: Cobalt (Co)
• Major Alloying Elements: Chromium (Cr) for oxidation resistance, Tungsten (W) for strength and wear resistance, and Carbon (C) for carbide formation.
• Typical Composition: ~30% Cr, ~4.5% W, ~1.2% C, balance Co.

Properties:

• High Hardness: Retains hardness at elevated temperatures.
• Wear Resistance: Superior resistance to abrasion, galling, and erosion.
• Corrosion Resistance: Excellent performance in oxidizing and reducing environments.
• Thermal Stability: Maintains mechanical properties at temperatures up to 1000°F (540°C) and higher.

Forging Process:

• Stellite 6B is typically hot forged to achieve the desired ring geometry.
• Forging improves grain structure, enhancing mechanical properties.
• Post-forging heat treatment may be applied to optimize hardness and stress relief.
